Very fun game, I'm stuck at 4 out of seemingly 6 powerups. The last two are crazy hard. Can't wait to finish it.
I would like to point out a bug I've found that forces you to quit the game to the menu to keep playing. If you die on some spikes while using the body slam ability in the ice mode, when you respawn you will be "frozen" in place, ironically. The only way to get out of this is to quit to the menu.
