Not bad sprite work.
I thought it was pretty good. I saw number one yesterday and thought it wasn´t too bad. Sure, like you said it´s not following any sort of story, but it´s pretty good. The sprites are simple, but work together perfect. The only things i would criticise, and not that much, are, you made the flash too small for your document, if you know what i mean. at one point when fighter jumps out the screen, you see half of him stuck at the side.....and the last thing is that it wsa pretty short. But overall not bad. Keep it up!
