I played briefly with default everything. The interface is mouse based, so the trackpad worked great for navigation.
At the name prompt, I did have to ensure the cursor in the entry field was blinking, then manually invoke the keyboard. Worked well.
Play was smooth and felt identical to PC.
This is a great and relaxing idle-game based on the design of a plant nursery tycoon game concept, and it works well. Great soundtrack!
When switching from Windowed to Fullscreen in Steam Deck Gamemode, the position of the game screen will gravitate towards the top-left screen corner in a smaller game-screen-size instead of being centered and fit-to-scale, but it is easily fixed by switching back to Windowed mode. It is centered and works totally fine when launching the game with Fullscreen enabled prior to game-launch.
This game could fit in a floppy-disk storage, the game install size is so tiny!
