It's different.
It's not really what I expected at all. Of course, I suppose that you were pressed for time. Were you wanting to keep pushing this forward or was this original plan in the first place?
Anyway, the idea is pretty cute. Simple Mario Kart reference, and a robot wanting to kill patchman in the end. Although, I know it's the whole point of the entire movie, but just one stab on his shoulder (or so it seemed to LOOK like his shoulder)....don't you think that's just a little.....over-the-top stupid?
The artwork's amazing though. It didn't really make me laugh that much though. I just chuckled a few times. So, humor's not really in there for me.
Overall: 4/5, 8/10
