Thanks! The web version was choppy even on my 10 year old gaming PC, but switching from Firefox to Edge fixed it a bit so I felt confident enough to publish that too.
Thanks for the crash report! The way I've made this game is mixing doing stuff in the Godot editor, some logic is in AnimationPlayers and the rest is in the worst scripts I've ever written, so fixing this bug is going to be a blast! :--D
