Looks kinda cool actually...
Not sure where ur goin with the story but i guess ill have to wait for the movie... a couple suggestions, the animation was slow, WAY too slow and they all fired at the same time, kinda annoying, if u could get them to fire a little more at random thatd be good. I liked the sound effects, dunno if theyre from metal slug or what but w/e.
I know your on a size restraint so my suggestion would be to do a kickass job and release it in parts rather than have to deal with size constraints and make your movie suffer. Good luck mate.
