The drawing/animating was done very well, as was the sound quality. There were a couple of humorous parts (the ending credit thing for one), but overall I don't think this flash really had much oomph. It was really zany throwing together a chef, the great wall of china, and zombies, and there could have been some better humor in there, in my opinion - especially since the chef appears to have several magical abilities (completely unrelated to cooking, btw).
A bit more cohesiveness would be great. Right now it just seems like randomness in order to get a laugh, but I think it's a slightly off mark. Not entirely off, but not exactly on target either. Oh, and bonus points for having a chef be your protagonist - we're an oft unrepresented lot :D
