I made the mistake of beginning this game with my audio muted, which is a shame because when I put on headphones a third of the way through I realized how great an impact the multimedia component has on this game. This isn't because there's anything weak in the writing that's being compensated for, but that the author has done a great job creating a disquieting space with all the tools at their disposal.
The basic premise is that the protagonist's mother has invoked a deal with the devil to remove their child's fat. The protagonist then enjoys a life of thin privilege, being first pick to be a news anchor at their television station among other benefits. Then, the devil announces that all pacts with devils are off, and soon their fat self will reassert itself. Instead of being consumed by suicidal thoughts, the protagonist makes it into therapy where they begin to unlearn self-hatred as they realize it's not serving them.
As I mentioned earlier, the disquieting moments are really amplified by the audio and the visuals. A lot of attention has been paid to these elements and it's really impressive. Regarding form, it's not a choice game, which is fine. I don't think it would benefit from being one. If you'd like to call it a "multimedia narrative experience" rather than a game, it might set your expectations better.
My only real critique is that it felt like it was missing a conflict in the final act. Once the protagonist enters therapy, it's essentially a linear climb to something nearer to self-acceptance. I might have preferred a challenge, perhaps the devil returning and saying the deal was back on the table, and seeing how the protagonist dealt with that as a chance to show growth or change. Otherwise, impressive output for something created in under four hours.
