I'm only iffy about the Japanese at the end. Are you sure this isn't stolen?
Well, I'll give the benefit of the doubt because I wouldn't know where to look for it. Moving on... I like the art style, as simplistic as it is. The action tends to go pretty well with the music too.
Certainly a step up from a lot of those sprite movies, I'll tell you. Bubbleman sure looked funny, though, and the power was all wrong. I'm guessing it was intentional though.
