The latest Chess Mess update (0.8.3b) is here. It includes a bunch of small fixes that improve the overall gameplay experience.

• Enhanced the game's stability on Steam Deck.
  
• Refined the focus experience.
  
• Updated the game board to wrap selection of columns and rows.
  
• Implemented keyboard input. Most of the game is playable with just arrow keys and the enter key. Notable exceptions include:
  
  • Card selection screen
    
  • Card slot selection
    
  • Options menu
    
  • Tutorials
    
  • Hints
    
• Enabled native touchscreen support
  
• Exported save data and preferences to external files that can be synced with Steam Cloud (WIP)
  
• This keyboard implementation lays the groundwork for gamepad input as well. Standard Xbox and DualSense controllers should work, but this is considered unstable and not guaranteed.
  
• Disabled the enableSteamOverlay function on Deck as this was causing the game to crash in Gamescope and it's not needed anyway.
  
  • Note that the Steam Overlay is currently broken on Desktop. We're working to resolve this issue.
