Space to jump, and don't fall down :) Hit the green flag a couple of times, or the world record-holder may have some glitches... probably due to having too many different "when green flag" clicked competing to start first, though I could be wrong :)
Jan 26, 2021: 1.0 release, equipped with a high score and high score holder (or so I thought) Jan 27, 2021: Apparently when you copy code (high score + holder was written in a different project) it turns cloud variables into regular variables, so I need to replace all the uses of cloud variables with new ones :( Oct 22, 2021: Made a few edits here and there since the last update but the major ones are: Adding a small jump and letting you use up arrow along with space to jump.
