Player 1 and Player 2 have unequal start points. (p2startx = -p1startx)

Use floortension (try 30-50).

The stage is essentially a single layer stage...and the whole thing is animated.  That presents problems, especially when only certain parts of the stage need tweaking.  The fog near the starry night sky does not loop well at all.

Since it's also just a single layer, (animated) single image stage, the whole stage suffers from significant color loss.  This can be helped by splitting the original image into separate layers.  If that is not enough, then try splitting each layer into smaller pieces and save each piece in 256 colors.

It's also not a good idea to use both shadow and reflection at the same time.

This looks so freakin sick. But i can't download it. Whenever i try downloading it, it goes to sendspace, and a little window comes up and says:"This slug-in has performed an illegal operation. You are advised to restart firefox immediately." And then before I even do anything, firefox freezes, and that error report thing comes up. Help?

edit: i tryed using internet explorer, now it works. great stage
