I actually liked this game, the writing is pretty good, for not really using any extravagant language it certainly manages to be pretty powerful in the context or i suppose lack there of. I was going to suggest adding music because the game feels empty, but I imagine that was what you were going for anyway, and i do think it sort of forced me to take the game more seriously than i would have otherwise.
I do however think this game would really benefit from original graphics, or at least i'd suggest you try make original graphics for any future game you might make, you obviously can draw judging from the images in game, and you have a pretty cool art style as well, maybe one that doesnt translate well into the small size of the sprites in rpg maker but regardless i feel like you'd be able to portray the tone of the game much better with your own work, thats just personal opinion though.
I liked the story, didnt really understand it that much (guess ill have to get the other two endings) but it is fairly interesting, what im picking up so far anyway is something about suicide, self harm, hospitals, comas, maybe a relationship that ended during a coma, and possibly something about being transgender but im not so sure about the last one, but i think all these things were pretty well portrayed, because it wasn't like, ridiculously cryptic but it was still vague enough that you had to sort of connect the dots yourself, and i always like that kind of storytelling.
Basically, good game, keep it up!
