when I ran out of time, and reset, where the gun was I would pick up the gun ability (on the left) it would give me the double jump. It’s only just now occurring to me that the abilities might shuffle each time.
Oh yeah, that's intentional. Upgrade locations are randomized on each run. I added that feature because I figured the extra variety would go well with the game's structure, though I didn't really convey the existence of it at all in-game.
