I managed to finish the game and it crashed only once.
What does not
The texts have a pink outlier that doesn't make it harder to read, but it doesn't look great.
Dialog screens aren't rendered properly and you only see a white rectangle. Pressing y/n works though.
Hitboxes don't work as intended, you basically go pixel hunting whenever you need to use an object, except that there's no indication which pixels are the right ones. There are only a few places where you're working against the clock though, so it's mostly okay to click like you're playing a clicker game till April does what you want. Occasionally this becomes annoying, but doesn't prevent you from playing the game altogether.
Additionally, switching to another workspace screws up the resolution settings (I'm using i3wm if that matters).
What was not tested
I finished the game, I believe I tested mostly everything.
