Everything that I've tested works, although there are two things that have some issues.
What I've tested:
What does not
1. Turning vsync on causes "jittery" lag. This problem existed in Proton but it was recently fixed.
2. Wine sometimes doesn't register fast clicks. This makes some hard levels impossible to play
Steps to replicate this issue:
What was not tested
I tested everything I could think of from creating accounts to downloading levels and playing them.
Overall Wine performs a lot better than Proton with this game.
