You have a unique premise to your game and some lovely character busts! They unfortunately clash with the other art on the maps, but on their own / the title card, they look quite nice.
It might've been a time-constraint, but all of the text with "Meat" when she comes to visit after your sister's accident is a LOT to read and it would be a lot more engaging for the player to learn some of these details throughout playing the game, rather than all at once. It's definitely important / integral information for your story, so you want to keep it in for sure (and probably also give it another proofreading pass), but a slower introduction would be much appreciated.
I love that there are multiple endings (I got #1: I am in pain) -- that's always a challenge to make sure comes together correctly, especially on a time crunch like IGMC.
Thanks for sharing your game with us! :)
