Also, the game has some wine/proton compatibility issues. Managed to get it started with Proton Hotfix, but the UI is a mess. I understand that you may not be able/willing to fix it on your end, just leaving it if you can and want to make it playable on Linux via Proton.
//edit: In regards to how exactly it’s messed up. If I try to run the game via wine (11.7), the main menu looks fine, but once the game starts the screen is completely black (game’s not frozen as when I try to “play” blindly I can hear ball bounce around after putting it). On the other hand, if I try to run it via Proton Hotfix, the main menu is messed up graphically (though buttons are visible even if messed up, but on anything other than Proton Hotfix and plain wine the main menu is either completely black or has a black rectangle on top of it), but in game it’s fine.
