Love the way this story is presented! Not much is said in the dialog at all but we get some glimpse of this world that is showed subtly in each minigame scene. The drawing is simple but charming and a stark contrast to the underlying horror. The ending scene is very well directed and cinematic, I liked it a lot.
One thing I would suggest is adding a Renpy hard pause when the ending scene started, and give it enough time for the whole ending to play out. Because otherwise impatient player can accidentally make a double click and skipped the whole ending back to main menu.
