I'm thankfull it wasn't the freakin' BFG!
Ummm... yeah...
Graphics: Drawn graphics mixed with sprites aren't always good, but it wasn't too bad, I suppose...
Style: Well animated, good use of effects...
Sound: Doom sounds and such... Can you tell me where I could get that song that starts before the credits? (Doom e1 ending, i think, seeing the credits.)
Violence: Pixelated gore from doom, and that's about it.
Interactivity: HAHAHAHAHAHAHAHA!!! (No offence, it's just because it's a movie.)
Humour: Nothing says badass like the cat-mouth :3, the moral was also pretty good, but it would be a lot worse if he had used the BFG.
Overall: Not your best work, but still, pretty nice. View this movie, now!
