Clean Air

Notes on genre
I would classify Clean Air as a horror game. It does seem that way at first, though. For first time players, your reaction will likely be "seems normal, that's nice, how quaint, WOAH. That escalated quickly!" That’s one of the game’s biggest strengths. The shift from mundane existence to something more sinister.

There is a faint One Eye Open (my favorite horror game) vibe to the horror half of the game. It's gory in a descriptive way, but, unlike One Eye Open, it does not require you to roll up your sleeves and do violent tasks (and significantly less gory). It’s not exactly for the faint of heart, but its potency lies more in leaving things up to the player’s imagination. I think most players will be glad that they gave it a shot.

Gameplay
Clean Air takes place over three days and begins with you in your apartment. I will break down these days in the Story section of my review. There is no directive or objective provided at the start of the game, but this suits the game just fine. The fact that there is no immediate story presented at the start simply compels the player to set out and find the story on their own. The map is fairly small, consisting of an apartment building and a swath of urban landscape.

It took me about an hour to complete the gameplay. However, it is one of those games that you can complete within a few minutes once you know what to do. Part of that hour was due to some clunkiness with the implementation, so pay attention to details in room descriptions and tinker with verbs. There was only one puzzle (not that there are many) that slowed down my progress: (Spoiler - click to show) The tap. (Turn on tap? No. Turn tap? Yes.)

There is room for improvement. Scenery is not always implemented. Being able to examine the location descriptions would have gone a long way. Especially for moments like when (Spoiler - click to show) you stand before the monolith. This is what you get:

>x monolith
You can't see any such thing.

I mean, the thing is towering right over you.

That said, the game does take care not to bog down the player with details.

There is one puzzle that the author may have originally planned something more complex but then backed. It has to do with the (Spoiler - click to show) key puzzle. BIG SPOILERS:

(Spoiler - click to show) It’s simple. On Day 1, you take the key and duplicate it using the locksmith machine. That way, you have two keys that you put together to make a combined key. You need this to open a crucial door in the restaurant. Now, you find corpse with a note that says they hid one of their keys in the grille in the storeroom. Supposedly, you can access this key in the grille, but the grille is empty. Then I realized that the grille is meant as a place to hide your stuff so you can retrieve it for Days 2 and 3 and still have full access to the map.

Thing is, it did not seem to make a difference when I returned to these areas of the map during Day 2 and Day 3. It still took me to the same ending, which was a letdown. Why bother with the grille? Also, why does the locksmith machine generate two copies of your key (for three keys total) when all you need to make a combined key are two keys? Maybe the author had something else in mind, maybe not.

This does not get in the way of completing and enjoying the game, but I would like to know if I overlooked something.

Story
The game's biggest strength is its story. It is spot on. In fact, if you don’t feel like reading this entire review, focus on this section. While the premise may be familiar for some audiences, the execution of the storyline is what sets it apart: Existential horror with a quiet, resigned leave-it-up-to-the-player’s-imagination kind of acceptance. I think it takes the game from "okay" to "hidden gem."

I am hesitant about sharing the story because A, spoiling the big reveal may take away the desire to play it, and B, readers might find the story contrived by reading about it in a review rather than experiencing it within the context of the gameplay. The great thing about Clean Air is that once you’ve played it and know the truth, you see everything with a new perspective.

I like discussing things and sharing ideas, especially when it’s a game that’s received no coverage, so read this at your own risk. MAJOR SPOILERS! If this game seems interesting to you, I STRONGLY encourage you to play it first.

→ Ripping off the Band-Aid: The awful truth
The Earth that we all know and love does not exist. Your apartment and everything else around it- the streets, the burger restaurant, the skyscrapers in the distance- is a habitat. A manufactured world. And behind it all? Some higher entities have decided to harvest humanity for their flesh, assumedly as a food source.

My first thought was to default to science fiction. Technologically advanced aliens who decided to visit Earth? Mad scientists with a chip on their shoulders? The reality of Clean Air is a bit more abstract, leaning away from sci-fi and more into speculative fiction with a splash of existentialism.

Truth is, we really don’t know who They are or where They came from. In fact, the game only refers to Them collectively as “They.” All we get are impressions. There is almost a godlike element to Them which makes sense since They are the creators of the protagonist’s reality. I feel that this approach will make audiences more receptive to the subject matter, which they might otherwise avoid.

→ Clock motifs
There is a lot of symbolism with clocks. It also shapes the gameplay for Days 2 and 3 (more on that later). Humans are born and live their lives in their manufactured world until they are old enough to be harvested. This is done in batches as they reach the age of maturity. The mysterious entities have clocks counting down for each batch for when their time is up. Then they disappear to be slaughtered.

Clocks represent the actual clock mechanisms that work behind the scenes, which we see in the slaughterhouse/workshop. Literally counting down for each batch. But the presence of clocks throughout the gameplay also symbolizes the notion that time is running out for everyone.

Room 204
A room, stripped bare of even dust. The air here is thin, almost empty. An analog clock stares down at you from its post on the wall, the only inhabitant of the room.

Time ran out for the occupant in Room 204. It’s not obvious though until you learn the truth. Suddenly, the emptiness of the apartment gains meaning.

→ Thoughts on the PC
We know almost nothing about the protagonist. Nor do they have any reaction to the game’s horrifying revelations. Now, this lack of characterization would typically be a detracting quality, but Clean Air makes it work because it amplifies the feeling of existentialism and mystery that underscores the horror elements of the game’s genre.

You’d think that the PC would be wondering “What happened?” or “Where is everyone?” Nope. But in a way, this lack of engagement gives the player the vague sense that the PC may have already cultivated some suspicions about their reality.

Ultimately, the protagonist serves as an empty vessel for the player to draw their own conclusions rather than forcing a particular perspective. Plus, this minimal characterization stresses the fact that a person’s identity has been implanted by entities solely interested in harvesting humans as livestock. It also makes the reveal more shocking for first-time players.

→ Thoughts on NPCs
Saying that there are NPCs in this game is a bit of a stretch, but they arguably classify as such. In this section, I’ll focus on the ones that engage directly with you.

Let’s go back to the mysterious “They.” What makes Them so intriguing is Their motive and perspective on what they are doing. The big WHAM moment is when you sneak up on two of Them having a chat (in this scene, the game cleverly uses alternating black and red text to mark their conversation).

Four more?
Only three, in fact.
How so?
One broke out.
Again?
It seems so.
One sometimes wonders if they are capable of thought.

The conversation continues, vaguely mentioning the existence of clocks, implants, and erasing memory. Then the kicker:

Lower your volume. One is looking at us right now.
Oh. Take it back to its pen.

That’s right, it’s you They are talking about. They (and we all know what They do to humans) see you watching Them. Creates such a feeling of Uh oh… This scene was the highlight of the game. And yes, they send you back to your pen. Also known as your apartment.

Realizing that humans have become a food source is hard enough, but the mundanity of it all is a shock. Our entire world is simply a business-as-usual operation. We see that They genuinely think humans lack understanding and awareness of what’s going on, that we are indifferent to what is happening. There truly is no malice or ill-intent. Just a casual attitude of “welp, one just escaped its cage. Time for another a batch.”

I found this intriguing because it goes against the “humans are pitiful, unintelligent, and must be put out of their misery and/or used for profit” narrative that is seen in science fiction and horror stories that involve humans being slaughtered for meat. It brings something new to the table. And yet, the horror is magnified because of this dissonance in the predator and prey relationship- and how they both fail to perceive each other’s realities.

Equally interesting is the possibility of Them realizing that humans are sentient and capable of thought. Of course, it’s possible that some of these entities are given more information than others but we really have no way of learning about the society They live in.

One other NPC appears during the most unsettling (in the best way) scene. Naturally, the scene occurs in a slaughterhouse/workshop- though it is more ethereal than your typical slaughterhouse. You are fooling around by the conveyor belts when suddenly:

It is here.

(…?)

You hear It coming.

(!!!)

Oh, you know, just something sinister that is closing in. The sense of dread in this scene was powerful and memorable. Protecting yourself from it is also one of the few puzzles in the game. Be sure to prepare in advance.

I do, however, have questions about this “It,” since the interaction is so brief (It either kills you or you evade It). So: Is It a member of “Them” doing an assigned job, or is It completely different type of being? Is there malice when It kills you or just a “get this pesky creature out of my workspace” sentiment? Either way, the sense of dread you get is effective. Especially since it catches you off guard (I really hope you played the game before reading this).

→ Thoughts on theories
This is when things get a bit more interpretive.

On Day 3 we learn that each batch of humans has been implanted with memories to create a sense of normalcy and lack of suspicion when their peers go missing. These memories also make humans think that they have lived longer than they have. Batches are harvested everyday depending on the maturity of each human.

Each batch, produced. Domesticated. Harvested. Then cleansed.

I would genuinely like to hear players’ take on this part. If anyone wants to offer ideas, I’m here. Going back to the conversation we eavesdrop on, I assume the “four more” refers to the occupants of the four-unit apartment building. Regarding the statement “One broke out,” are they talking about the protagonist or the tenant of Room 201? Let’s compare.

Tenant as the escapee: I’m pretty sure that the corpse we find in the slaughterhouse/workshop is the tenant. Room 201 is the room where we find the key and the illegible papers. The tenant clearly discovered the truth of what lies beyond the meat locker room in the restaurant and did so before the time for their batch ran out. The note on the corpse explains these efforts. Not that it saved them from being slaughtered. Does “One broke out” refer to this sneaking around?

Protagonist as the escapee: Well, we seem to be the only living soul around, almost like we missed being harvested. And we are sneaking around in places that are meant to be off-limits. After all, by leaving our apartment we’ve escaped our “pen.”

So, who’s the troublemaker who broke out?

I also have some thoughts on how the game is structured around days. As I mentioned earlier, there are 3 days. After the entity says “Oh. Take it back to its pen,” time resets, and you are dropped back into your apartment with the message “It begins. The hand is 3 minutes from completion.” You are trapped in your apartment for these three turns, triggering Day 2.

Day 1 was fantastic in terms of length and content. But one thing I did not like about the game was the pacing for Days 2 and 3. They felt rushed and failed to make key aspects of the story come to life. The objective of these two days is to show off the clock mechanism in action to illustrate how it dictates humans’ lives and their inevitable demise. But the way it is implemented in the game loses some of its impact.

Days 2 and 3 involve wandering around the map while the game feeds you scraps of exposition. When Day 2 begins, you can leave your apartment. However, the key needed for the door puzzle is gone from Room 201, making half of the map inaccessible UNLESS (I discussed in the Gameplay section) you took certain steps during Day 1. Not that it matters since the gameplay is focused on you taking in this new knowledge. Then time “resets” and… you end up in your apartment again. Repeat wandering around, absorb info, time resets, (etc.), and suddenly it’s Day 3!

Unfortunately, Day 3 is much of the same thing when finally: You are out of time. It is your turn to be harvested. The one difference is that on Day 3, Room 202 is mysteriously open for you to explore.

I don’t have a problem with the general blueprint of Days 2 and 3. It makes sense because it supports what we’ve learned in the story. I understand why it ends this way. But they are so brief and repetitive that it leaves the player asking, “that’s all?” The loops were hard to keep track of especially since the “It begins. The hand is 3 minutes from completion” phrase was injected randomly. What exactly is going on? It gives the impression that the author was not sure of how to wrap up an excellent idea.

Some things could have been clarified. I am a bit confused about the concept of batches and what they mean for the apartment occupants. It seems that the tenants of Room 201 and 204 were harvested before the game began since they have empty rooms, and that whoever lived in Room 202 was taken to be harvested between Days 2 and 3. And of course, at the end of Day 3, it’s your turn. Am I correct about this? And why do we keep getting away with escaping our apartment “pen.”

Additional insight from the author would be nice.

(It also occurred to me that the protagonist portrayed in Days 2 and 3 were separate humans with identical memories, but I don’t think that’s the case).

→ Thoughts on endings
I believe there is only one ending- the fate of all humans. I found two ways to die prematurely, though. Note that NONE of these outcomes are graphic.

→ One more thing…
Does anyone get the meaning of the title? The closest thing I can think of is the vapor emitted from the meat as it’s being processed. Otherwise, I don’t see the relevance. Just curious, that’s all.

Conclusion
I must say, if this is a first-time game for the author, it’s fantastic. Now, I realize it is several years old, but if the author ever reads this- great job. You really have a knack for horror.

If you like horror games that slowly peel away the normalcy of the setting to reveal a more sinister truth, Clean Air is the game for you. Now, I have been wavering between giving this game 3 or 4 stars. I'm doing a tentative 3 because the implementation could be a bit sharper, and the pacing becomes a tad too abrupt in the second half of the gameplay. But the story? Fine work.
