For those that suck at the game, or are bat with at least 1 character, here's a cheap way I found how to beat the final boss Marie:
Also an easy way to beat the final boss(Marie) if you are having trouble with a character, is to set the game to 30 seconds, hit her right away for only a little bit, I'd say only 20% of her health so that she stays in the same 'mode' as the start of the battle, then back into the corner and hold back/block till time runs out. I wasn't good with 2 characters and used this method.
