The characters in the game were fine. The game has massive balancing issues. Games with tier lists are fine, games where character x has no chance against characters y is what kills the game.
The balancing issues are so bad that instead of doing something to fix them, they made attacks completely worthless. Fat Princesses knight in the air was too good, so how did they fix it? They made it worthless. Drake's barrels aren't even worth using anymore. Raiden's down triangle in air went from no recovery to a few seconds recovery, etc.
I like the style of the game and how it was made, but they need a developer who's good at the genre to fix it and/or redesign the entire thing.
Superbot had no problem making Isaac and Kat top tier. Or maybe because they're garbage developers and don't know how to balance worth crap.
