Easy, glitchy game. Level 1 hold right jump when needed. Level 2 just stay to the right. Level 3 don't move jump when needed, Level 4 is easy with 12 lives with some timing.
Similar to Starcraft grouping hotkeys. WIshing for right-click but oh well. Really easy badge. Got the hard first try, and I'm on wave 42 as I type this and am about to suicide cause this is pretty easy.
