Actually quite addicting.
I had fun with this one. After dieing I found myself wanting to play it again and again. But it can get quite boring after awhile.
The mouse seems to be much easier than the rest of the controls, or atleast I think so.
Also the graphics were a nice touch. What would have made this game a lot better would have to be the use of upgrades. I mean you already have items you hit in order to gain special powers, but there should be waves to different levels. After each wave you would get to chose an upgrade followed by the task to destroy a new enemy.
I enjoyed this game very much. I enjoyed playing it, and the music is just perfect for it.
You did a great job and I hope to see more from you.
