(A version of this review first appeared in my blog during IFComp 2020.)
Alone is an adventure of survival set in a sparsely populated post-apocalyptic world. The initial situation of having your car break down out on the road leads gradually (but not too gradually) into a series of dense and satisfyingly overlapping puzzles, especially of the mechanical variety. With its keys, locks, recalcitrant security doors, fuseboxes, circuits and deserted environments, Alone's puzzlebox reminded me most of the Resident Evil games. Alone also steps into the equivalent IF tradition of the Resident-Evil-type game, though pointedly without gunplay, shooting or much violence at all. I'm now finding it harder to think of other similar parser IF games than I expected; there's Divis Mortis, and, with a supernatural spin added, One Eye Open. Calm has deliberately very fiddly mechanics in a post-apocalyptic world, but not any bogeymen if I recall correctly. Alone has The Infected. Zombies if you prefer.
Alone's puzzles are broadly familiar in the adventure game aesthetic, but that doesn't matter when their execution and interweaving are as solidly performed as they are here. The game isn't perfect; a couple of the most difficult actions only accept one very specific phrasing, and I had to use the walkthrough to get through those parts. But otherwise, there's consistent logic to all the mechanics. Alternate solutions to problems are considered by the game and well-excused. Nearly successful attempts on puzzles give feedback to point the player in the right direction. Irrelevant objects fob the player off to avoid time-wasting. These standards are maintained for the game's duration and that is very good work.
A few spoilers if you read on:
Alone has an interesting quality that was apparent to me only after completing it. I noticed all the things that hadn't happened in it. I mean things that I might have expected from a game like this if it had not veered from the centre of this genre's road. The threat of infection is always present and its zombifying consequences are apparent (the one time I did turn into a zombie, I found the description pretty creepy) but there is ultimately only one active zombie encountered in the game. The PC isn't disrespectful of the dead and the player doesn't have to fight or kill to survive. There's almost no violence. And though there are a few endings, the game's ABOUT encourages the player to get the most obviously good one, which it turns out is tied to the most moral and hopeful outcome in the game. So Alone reminded me what my expectations for this genre are, and was uncharacteristically optimistic or entropy-averse in relation to them. In this way it stands out from what you might call the current glut of material in this genre in other media. Though as I say, I think the genre is not as strongly represented in IF as I thought it might be.
