If desktop panels are visible, change to fullscreen in game settings, otherwise flawless.
Initial bootup is in "borderless window fullscreen", which left KDE panels visible. Switching to "fullscreen" fixed this immediately.
Seems to work without issues
Game started in tiny window, but it's easy to make it fullscreen, which sticks in subsequent play sessions. No tweaks otherwise. Had to wipe the save for a refresher, but played through the first 15 levels without any major issues.
Intel graphics not good enough to play the game. Requires disabling D3D11 to launch at all, but FPS too low to be useful.
Working perfectly out of the box.
Initially starts in a small window but can be easily changed to fullscreen. Runs flawlessly on Proton 3.16-9 Beta, including Xbox One controller support. Has major graphics glitches on Proton 4.2-3, even on WineD3D.
When starting up initially the window was tiny, had to go into settings and change the size. Runs perfectly after that.
Run fine but doesn't detect the controller
runs well
Started out in a very small resolution. Had to click to Options > Advanced Options and toggle Full Screen. Even that was tricky because it then hides the window and starts a ridiculously fast countdown timer for you to refocus the window and accept changes before it reverts. After that, everything is fine.
The first time starts windowed. Xbox One controller not detected
