By the way, I've beaten this game with every character, beat the P-Bot challenge 100%, cleared the health challenge thing in 3 seconds, and owned Wodalf enough times to make you all look pathetic for failing...
DONT COMPLAIN ABOUT THIS GAME
Its good, it really is...
The reason for the single button gameplay is that its based on Castle Crashers. Be glad for what health you can find and be strategic with it.
