Thanks a lot for playing and for sharing your thoughts! Yeah UI scaling is something I haven't really figured out how to do properly so I forced a particular size and tbh didn't think about smaller screens D:
The Itch.io fullscreen option is enabled though so there should be a full screen option available. I've found if you use the browsers zoom in/out then that breaks the view too unfortunately, even if the game is full screened, I guess it's some issue with how the WebGL build assess what the actual screen size is when displaying the UI.
