The entire rhythm game, minus the rhythm game, functions.
Using the default Proton settings as decided by Steam, the game boots. Keybindings are usable and menus can be navigated through. Inputs are not detected during rhythm game play (after song selection). Reproduced on GE-Proton9-27, and Proton versions 7.0-6 through 9.0-. Occasional inputs were successful when Protontricks was used to change OS version to win8.1, but not enough to facilitate gameplay.
Enjoyable if you like listening songs and watching characters. You wanna play? Nope.
Video playback is lagging and sometimes black artifacts appear.
It gets no input from keyboard while playing. All I can do is watching every notes get Miss. Escape key doesn't work, couldn't even get out until the song is over. When not playing, for example in the menu, keyboard works just fine.
Maybe the devs had made non-standard ways to get keyboard input for minimum latency, which made some issues on Proton.
