I played Not Just Once back when it was first released and enjoyed it then, but encountered a few bugs. Having just played the updated version, I’m happy to report that my experience this time around was bug-free! Both on my original playthrough and again today, I found it quite compelling from the get-go; there’s a very moody vibe to it as the PC walks home in the snow on a January evening, preparing to eat a sad corner-store meal, and soon it takes a mysterious and somewhat spooky turn. (I found myself reading parts of it in the voice of Jonathan Sims from The Magnus Archives, which was delightful.)
Early in the game, the choices are about characterizing the PC—do you find Christmas lights still up in January charming, or irritating? What type of ostentatious shoes are your favorite? (Later, there’s also an appearance customization section, but it subverts expectations in several ways; clicking “skin color” does not actually allow you to choose a skin color, and the things you do get to choose have an immediate, very effective payoff.) We’re never told much about the PC outright; there are hints at your past, and apparently you knew going into it that today would be difficult, but the reason why, whatever happened prior to the game’s start, is never revealed.
Players also get to help shape the PC’s reality in an interesting way, going beyond looks or fashion choices. When a stranger tells the PC the two of you have met before, you get to choose if she seems familiar or not, and whether or not it’s possible that you had the encounter she describes. For these reasons, I felt somewhat distanced from the PC the whole time, like I was co-crafting them more than playing them, but that wasn’t a bad thing; having all these different options made it feel like the game was full of possibilities, and I was eager to explore them.
After playing several times, I definitely have a favorite ending, one that felt most fitting with the game as a whole. Multiple times throughout you’re given the choice to pursue/continue your odd encounter or give up and just head home, and continuing was the most rewarding to me; heading home (alone) at any point feels like it cuts the game off early, and leads to an ending I found less satisfying than what I consider the “main” one.
Two minor mechanical things—this is a stretch-text Twine game without an auto-scroll function, so constantly having to scroll down after clicking a choice was a bit annoying. The other is that the game doesn’t properly restart if you click the “end” link, which returns you to the beginning screen, and then click “start” again; if you do this, the game still remembers the appearance choices from your prior playthrough, and you don’t get to pick new ones. To fully clear the slate and start fresh, you have to click the “restart” icon. But these are small complaints about an overall rich, intriguing game!
The problem with hype is that it raises your expectations, and when the hyped thing fails to meet those expectations, it inhibits your enjoyment in a way you wouldn't have experienced if you'd gone in without those unfairly high hopes. I've experienced this with a lot of popular IF works, not just this one, so it's definitely more me than the game--and it was a very good game! The completely alien perspective, positioning humanity as foreign, is narrated in rich language that uses common English words in never-before-written ways and was compelling and lovely to read. The horror elements were well done, understated in their matter-of-factness, which made them all the more horrifying. Contrasted with this, the beauty of the Song, of the alien world, of the bond that forms between alien and human--it all makes for an excellent story.
But I think I might have enjoyed it more if it were a story alone, a work of static fiction rather than a game. The whole time I felt like I was being guided through an on-rails experience, always nudged in the correct next direction, not encouraged to experiment or take my time. While I appreciate the game's helpfulness in keeping players on the right track, allaying potential frustration, what I enjoy most about parser games tends to be the exploration and experimentation that the form typically encourages. Coloratura held my hand a bit too much for my liking; I would have preferred a little more freedom.
