A really satisfying and wholly pleasant experience. I decided to check it out after seeing the Randomise User video and had a lot of fun. My only real gripe is that the root division seems to be really unreliable until you get a certain amount of points into it.
I was also kind of hoping to find a Dolphin Olympics "edge of the universe"-style easter egg from growing up into the sky ;)
Great work overall! I very much enjoyed playing your game.
