Works as intended
No issues at all.
Works just fine
When first switching to windowed mode the game was not positioned correctly in the window. Half the game was cut of. Switching the resolution fixed it.
Visual glitchiness when switching from fullscreen; switch to windows, exit the game, and it'll work fine when you start it again.
Instaquits with default Proton, works (mostly) fine with experimental.
Remapped the B button to the Z key.
The text is mostly legible, but some text is somewhat small on the Steam Deck screen.
The game was designed with Mouse and Keyboard in mind. It works fine with Steam Deck's controls, and even the touch screen works fine. The controls are: arrows/WASD, R to reset, Z to undo, Space to do stuff, Escape to do something else. At one point, you have to manually activate the on-screen keyboard to be able to type something.
