It was pretty good
The graphics and sound were sound were pretty good. But the game play and contols could use some work.
The game play is the same in every level just getting a little harder and more complicated each level. You could probably fix this with different objectives or upgrades to the ship each level. But as it is it's more of a fun every once in a while game.
I'd like to be able to control the ship with th arrow keys. Trying to dodge, aim, move, and select weapon all with the mouse is kind of a pain. It's pretty difficult to have the cursor everywhere at once you know.
