delay when moving, very bad performance even on lowest setting
just crashed once after one puzzle, haven't open it again after
cannot see home menu and initial video if not using the 6.3.8 proton
easy to connect/join other room, but has slight delay when communicating
Changed abxy and trigger buttons to match controls in game
Switching to proton 6.3-8 was necessary as newer versions caused errors in showing animated 2d graphics on the menu, opening cutscene, and videos in-game rendering them completely unviewable, with grey lines, zoomed in, and the rgb values offset from each other. 6.3-8 was the latest version which showed these elements fine, and the game otherwise ran fine at 60 fps. The keyboard layout worked fine except several buttons including document reading and map controls were not mapped by default, so I had to change 3 or 4 buttons to match these keys in the game. There may have been an issue with the in game voice chat but I wasn't able to test it at the time.

When loading into the map the first ~30 seconds the game slows down to less than 1 fps when compiling shaders, after that the game is pretty playable.
it would probably work on other hardware, but not on my intel integrated
game constantly froze on my hardware (intel integrated)
