You can really tell what sprites are from the original and what sprites were edited. And the background loops poorly. I have to admit, I have seen worse Shoot games.
It's Snake. I've seen worse versions, I've seen better versions, but frankly once you've seen one version, you've seen them all. Not an awful first game by any means, but you really should have come up with something far more inventive for your first upload, in my opinion.
