Awesome
Excellent game. Liked this one a lot more then the recently submitted "Super Smash Flash". All the moves, powerups, (unlockable) stages and characters really make this a great game. There was even a level editor =) awesome.
I don´t think there´s much that can improve in this game. Only thing I can think of is that in the campaign mode, it is easy to finish the first 8 levels and 2 bonus levels. I finished 67% of the game in less then 10 minutes. I had some more trouble with the "hard" levels, but those matches usually ended up in 5-4 or something. And also they shouldn´t be any trouble at all if you get the right items thrown before your feet. Perhaps you should add more levels or make the stages a little longer. Like there´s 2 rounds or you first have 2 rounds against many easy-to-beat characters and fight the unlockable one as a boss at the end.
Overall 9 out of 10, 5 out of 5. I really enjoyed playing this game and I´m sure I will play this more often in the future. I hope you´ll make a lot more of these. Keep up the excellent work.
