Very nicely done
For a beta version of a game, this is actually pretty amazing. It had a good variety of levels, several characters with personalized moves, several chalanges, power-ups, etc. There were a lot of problems though; in some levels, you acutally can fall right through the bottom floor (namely the Outer Space zone) and any character capable of flight can fly pratically infinitly, allowing COMs to fly back onto the stage after what should have been an inevitable KO. I'll let it slide because of the fact that it's a Beta version of the game, but try to fix that if not anything else. Otherwise, I have no complaints. I'll anxiously wat for the final version.
P.S- Anyone interested in knowing how anything is unlocked, send me a message, and I'll give you a link that explains how to unlock everything in this game.
