A little too easy...
I played through the whole game and didn't die once. The only challenge at all was the old farts since they were invincible, that's it. All the rest of the enemies could be easily fended off with the fire balls. The slow down effect, while it came in handy sometimes, it was too long and triggered too easily. The music, or should I say, just rhythm, got annoying very quick. The ending music should be used more then just on the end. That was fitting and funny. The artwork was well done, and game play was smooth, but it definitely could be improved upon. More of a challenge and upgrades maybe?
Fast, fun and a new simple concept that just about works. Can get boring after a while, but anything can. 3/5
