This is a really fun game!! I've enjoyed it a ton :D
However I do feel like ending 4 needs an additional trigger warning of some sort (possibly marked as a spoiler somewhere?), as it was significantly more effed up than all the previous themes in the game. While I'm aware that might've been a purposeful choice, it definitely at the very least effed ME over a little bit, and I'm not able to stomach playing through ending 5 until I've had a few days to recalibrate.
I hope you'll take this into consideration, as it really is an awesome game :3
