Game crashed on first startup.
On the second one it ran fine though. While the fighting element leaves a lot to be desired, the spritework shown is actually really impressive, even if the character's themselves look significantly lower-res than the background.
For a game where you had to "salvage it out of messy coding", being able to control both characters was nice, however I should mention that holding the jump button would cause a character to float up out into the atmosphere, never to return.
A good attempt still, and I don't think it would have taken much more work to make this a functional fighter.
