Good but in need of work.
It's a nice idea and this would probably make a rather good flash series but there are some bad points I'd like to point out:
1. The movements were very limited, usually only by minimalistic movements such as (what I think is) a hell of a lot of motion tweening. It's used in anime and it could be justified in small doses but it severly limits what this flash could have been by the fact it's used horrendously often.
2. To me the characters look a bit stereotypical and bland. Two of the characters looked very Megamanish while the others I have seen scattered around a lot. The robots were also pretty much metal Raymen.
3. It was a bit short for a fight scene and it could've had a lot more action and a bit less randomness.
Not to say this is bad. It's one of better first flash movies I've seen (first on Newgrounds anyway) and it could be successful but it's lacking in some areas you could say.
