The game generally runs well but with the crashes that will occur whenever the music ends, it may be annoying or frustrating to play on Deck
Some text was smaller than I would have liked.
When a song would end the game would crash. Muting the music would cause issues when closing the game making it so the game wouldn't close properly.
A crash would consistently occur when music ended.
The game generally will play well on Steam Deck but it will consistently crash when the music for the level ends with all progress for that run lost. This isssue may temporarily be fixed by turning off the music in the settings, but then I found that I had difficulty when closing the game that it would not close properly.
I would say that it's playable but be warned of the crashes that can occur.

Text was a little smaller than I would have liked.
The game will freeze once the song stops playing in the gamemaking it totally stop.
The game will crash once a song will stop playing. Turning off the sound may fix this. Also turning off the sound will make the game not close properly (as far as I can tell)
When the song for the level ends the game will crash. This is most notable in longer levels and in the endless ride mode. Turning off music may fix this but I haven't played long enough in a level to confirm this.
When turning off music the game does not want to close.
The game is generally playable in the state that it is in but there are some glaring bugs that make it difficult to recommend. Mianly the game crashing once music ends and turning off music makes it difficult to close the game correctly.
I would potentially stay away from the game if you fear that you might mess up your deck while playing this.

if you let the music in the game end at any point (music does not loop) the game will instantly freeze
tried on all proton versions, same thing
Worked, but now borked
Previously worked albeit with some screensizing issues in i3, but now it won't even launch anymore
