TL;DR = This game works great on Steam Deck!
Greetings! Since this game hasn't yet been through the official valve Steam Deck compatibility review it does not yet have the verified on deck badge, but hopefully it will soon!
An official controller layout has been published;
All game features work with Steam Deck controller only, no need for touch screen or mouse input;
The tutorial will show the the Steam Deck buttons/glyphs;
You can host/join multiplayer games;
When making this game I spent a lot of time ensuring that it works great on Steam Deck, I used my deck to help me test multiplayer when publishing new builds.
If you have any issues or suggestions for improvement related to Steam Deck please let me know
