A quick post to let you know:
For a fair amount of time, all MemoryMaze builds were tested on a Steam Deck too, and it runs great!
The game runs at Steam Deck native resolution - 1280x800
All control glyphs are dynamically adapted to represent active control scheme (keyboard&mouse - controller)
No launcher menus, no need to use the touch screen
UI is dynamically scaled to fit the screen size perfectly
Cloud saves are enabled, continue your game any time at any place!
