Not so good...
Artwork was rough at best, difficulty was through the roof excessive, and it was VERY hard to control the spaceship, its pretty much impossible to score a kill without losing a life... try making the space ship shoot downwards next time, like when it flies off it extends out, that'd be cool :D. Try making it easier, working on the art, and making the gameplay a little more complex, like maybe a upgrades shop and progressing levels of difficulty or something.
