This game lets you select how 'intense' you want it to be on a scale of 1 to 5.
The level 1 game version is very brief and succinct, and provides almost no information.
The level 5 is visceral, removing control from the player and filling the screen with text.
There are two layers to the game. One is the story, which is someone's authentic and personal story communicated in an effective way that fits with a lot of experiences I've seen in myself (a little) and in others (a lot) over the years. You can't really measure a story like this as a success or not, but you can say whether it was transmitted in an authentic-feeling and competent way, and it was.
The other layer is the selection of the different levels. Seeing the variety of them was really telling and compelling, because it showed what the author considered most disturbing and least disturbing, and the choice of some background information only being in level 4 was particularly interesting. I'm not sure how I felt about the response to level 3; it seems like a value judgment separate from the main message of the game. If the author had just (Spoiler - click to show)provided a description for level 3 that was in between 2 and 4, I wouldn't have thought 'that's silly, there's no such thing as middle ground.' It would have just been normal. But, the choice does provide an interesting talking point for discussing the game and leads to the name of the game.
I hope everyone who has suffered from eating disorders in the past or currently are suffering gets help, patience, and kindness from those around them, and if you're reading this while going through it, I support your efforts, whether big or small, repeated or rare.
