Keep it Olive by Nicso 2020-04-22T14:58:38Z
Short but fun! As others already said, jumping is tricky and required you to press the button quickly. I also got stuck sometimes. The "onGround" flag is probably set by the bottom bun, if that one is dangling off the side of a levetating platform you can't walk or jump and need to reset.
Great Game that made me contemplate if there is a correct order for ingredients in a burger.
