Oh hey, awesome, more P0!
... I apparently suck at it now though.
RIDICULOUS LEVEL RATE: EXP PURITY - Every single item in the pickup queue is an exp-up token. Of course, that means you'll never see another star for the rest of the damn game - and hearts will only come with level ups.
What if it made each item give 1 experience point in addition to its regular effect, or replaced all powerups with either hearts + experience powerups or stars + experience powerups? Too strong? All of the super abilities sound powerful, but this stands out as being the only one with a downside.
