this seems like a copy of that other flash involving metal slug and megaman x..the difference is that in that other flash there were zeros instead...i guess that was your inspiration...the other one was in my opinion better...maybe it's cuz the frame rate was too low..or that even though it's a war the movie was pretty slow paced at times...also check the running animation cuz i think there are some extra sprites and at some point it looks like there's 4 legs sticking out...
