Game will show up in a tiny box in the middle of the screen unless you use the "Configure Settings" launch option, go to Graphic/Audio Settings>Screen Processing, and uncheck Aspect Ratio Fix
After unchecking the Aspect Ratio Fix box in settings, and switching to a community layout, the game works perfectly
Game runs perfectly OOTB.
Game runs with zero issues OOTB.
Had no issues running Isuka on the most recent version of Proton.
Isuka's graphics are entirely broken on all Proton versions between 7.0 and 4.11-13. Use 4.11-13 to play.
Cutscenes (i.e. the intro) don't play in 4.11-13. They play fine in later versions of Proton, but the rest of the game is broken on those.
Unplayable out of the box due to severe graphical bugs. Switch to Proton 4.11-13 and the game will work fine, minus the lack of cutscenes.

configure controller

Works perfectly, tried both fullscreen and windowed mode. Note the controls are not defined out of the box, you need to configure them (right click on the game in Steam library and select "Configure Settings").


Input from keayboard and gamepad not working. Sound does not work.
