not bad
It was a fun game and fairly well done. In my opinion, the weapons are still a little unbalanced, but that may just be me. I'd say that the laser is basically useless, even when fully upgraded. Which means the whole game is just shoot and wait for rocket. Repeat.
One thing you may want to look into is the collision detection with enemies...or enemy attacks. Not really sure if they were supposed to attack or just run into me. I rarely lost health in the entire time I played. And I could fly right through the large mass of enemies without being damaged at all.
