Good, BUT
I liked this, but I did find some issues, so now I am gonna rate it, by saying what's good and what's bad:
GOOD
*Excellent animation
*Feels like a fighting game
*Kinda reminds me of Brawl
*Great siundtrack (whoa, Mario 64 and Galaxy flashbacks!)
BAD
*I found a couple glitches:
One time I died, and the music didn't play
Bowser threw fireballs, but they kept coming infinitely, slowing my computer, and causing an instant death
*Bowser doesn't have a run or jump animation
*I wish there were more enimies besides Koopa's, and power-up's
*Too easy/short
despite the bad, this was extremely fun, and I hope to see it evolve, if you can fix the issues
