The controls are not that great, it would be better to give the player the possibility to jump with w or up arrow. The game is quite short which is usual for a game jam, but the 2nd level is not obvious so it take some thinking before completing it. I really like the idea of getting bigger the more you collect bits, maybe another mechanic could be to be able to delete (definitively) the bottom of the stack, making new puzzles possible where you have to sacrifice some bits but in the correct order to get to some platform. Solid game overall, GG :)
