Hey, I was considering doing a run of this, but I'm a bit confused about the 100% category, since there aren't any rules about it: Does it mean to unlock all achievements? Or just to complete every single level/state? Also where would the run end? Since the game doesn't seem to have an ending.

It's getting all achievements and when you get to the final area run out of energy, then the run will end when you empty out the accu bar at the apparent end with the computer where you hit all the buttons. Then show that all achievements were collected at the end
