The thing is, it's not really fun.
But I just had too many problem with it. Don't get me wrong, I know he was 16 when he made this and was new to flash games, so I'll give him props for making something this complex (hey, the game is actually somewhat long in order to get some unlockables).
But the controls really weren't Super Smash Bros., the fact you only have one button to attack with and only has two variations of move made it look dull. If you're a Smash player, you'll understand. Part of what made the Smash series great were the controls. But for a standard game, it's somewhat passable. The game has an awesome roster of characters and the sprites are great overall.
It's just that it seems too dull after the first 30 seconds playing with a character with only 2 fighting moves and the only thing I wanted to do was just see everyone's move. You should play some other game though, I'd highly recommend to stay away from this.
