I like your drawing and animation style. You can animate, I'll give you that. But this animation was just...
Okay so first off... Why wasn't he wearing pants? That pretty much bothered me... Because it seemed to have no point...
Second... Why did his head explode when it hit 0? Shouldn't it have progressively happened throughout the course of the flash? Like... I was thinking "Hey, he made it.. He must've won ya-" and then... Yeah. Idk, the whole thing was pretty disturbing to me. You need sound also, but I'm pretty sure you're aware of this. For animation, it gets an 8-10
Overall, 3 - 10
2-5
