Cool idea for a game, simple art but it gets the job done.
Not sure what the healthbar does at the top but maybe it was explained in the huge wall of text at the start that I most definitely skipped. EDIT: I am just now discovering you can click to view the level, but the health goes down. I got this whole way without knowing that. I was using the mouse to "mark" important zones on the map like where to jump!
I got stuck on this level, whenever I'd jump to get the key (which is invisible in the screenshot for some reason?) but die upon landing on either side of the platform.
