I'm not OP, but it seems that you push yourself away from the surface if you 'shoot' downwards at the surface you are standing on. But... even with that I can only get to the green platform above, after which I get stuck too.

Hey, thanks so much for checking this out! Sorry to hear that there’s problems with the jumping and instructions. I have updated it if you wanted to try again? I’ve obviously still got some bugs to squash and instructions to make clearer but either way, thx so much for the feedback! (the ‘pushing’ also shoots you much higher by jumping and ‘shooting’ down at the same time)
