Hi, sorry about your PC...
Funnily enough, I remember the game working on mobile on itch.io in the very early days, but something must've broken it.
There used to be rudimentary touch support in some beta version (I believe it was 0.2.9) but people didn't like it as it made playing with a mouse unpleasant (basically you had to have your mouse perfectly still when clicking).
I could have two separate versions for touch and mouse input, but that'd add unnecessary complexity, especially when the game is still changing this much.
