The most recent update to the game includes compatibility for the Steam Deck.

New features include:
1) Complete controller support for the game and menus.
2) Touch controls for menus
3) On-screen keyboard for inputting text

The game should be running at 50-60FPS on the Medium graphical setting, or 30FPS on the High graphical setting on the Steam Deck.

Don't forget to go to the Display settings and change the aspect ratio to remove the black borders.

See you at the Coach Co-Op fest in February!
