The game is fully playable on Steam Deck and currently includes the following support:
Runs at the appropriate Steam Deck resolution.
Keyboard inputs are handled through a custom button display system (with some special character limitations).
Controller glyphs currently use Xbox-style button prompts.
Performance is comparable to the PC version.
The game does not yet have an official Steam Deck compatibility rating. The verification process can take time and usually depends on community interest and activity.
If you'd like to help support Steam Deck verification for the game, feel free to leave a comment in the Steam forums and let me know you're interested.
