Well..
I'm a huge fan of the Patapon franchise but don't worry as I'm not going to swear against you for making fun of Patapon :P
Anyway, the presentation with the logos of the companies should be replaced with your initials. As far as I know, I don't think you're allowed to do that even for a joke.
The animation was decent and the whole point was creative, too, until the scene with the Patapons fighting.. themselves?!
The "Snake" end ruined it all.. I get that it's a joke, but you even said in the flash movie there were no more enemies to fight. So why put Cioking in your animation and a Snake-looking Patapon fighting it?
I would give it 6/10 stars, however, the ending took it down to 4/10 stars. Also, 2/5 for the voting.
