Power Ups

Currently, I only have a jump boost. I also don't have much surface, but I can imagine. A speed boost for faster horizontal transportation would be nice. Something that makes the player invincible as well, although there are no enemies as of yet. Any permanent power ups, like ones that make power-ups last longer and ones that increase base speed, could be nice too. Flying would be too overpowered, though, considering how open the game is. It would let the player go straight past any obstacles that aren't walled off. Of which I think there are none.
