Cat thing with Megaman like helmet and fancy gun that smokes.
White background because I anti-aliased it.
the background is an improvement but i think you should distribute the stars a but more evenly rather than just at the top, also i like the animation
There, I updated it.
It certianly would. You're not even using the white in the sprite, so I dunno why you went with it for the background, there are much less stark/jarring colors to choose from (like a light greenish color to offset the purple. Or a nice neutral brown). The AA could be optimized at the very least.
Like it'd be any better even if it didn't have white background.
You can still AA and have a different background. The white BG isn't doing you any favors.
