This game is short, challenging and a pretty good blast, considering the game's length. I wouldn't mind seeing a sequel with some newer gimmicks to play with, like a dash roll. Perhaps even a few upgrades that let the player reach new grounds(pun *very much* intended), like a metal ball that lets you sink underwater, or a spiky ball that lets you climb up walls. This game has ridiculous potential, and I think it might make some pretty interesting sequels! 11/10!
