Hmm....
Graphics: Began with high expectations. The mouse looked so well drawn and animated. Then it went downhill from there. Finally ending in a red splot that is supposed to look like blood, but really doesn't, and a hand written replay button.
Style: Ah... The ol cat & mouse gag... With a little twist. Didn't expect the cat to fart, lol.
Sound: Could've had more sound effects. Like a chewing effect for when the mouse was eating the cheese, a running sound effect, and maybe a cat hiss effect.
Improve your animation a little more. It looked like you had a high motivation going into the movie, but got lazy as it went along. Hope to see more.
