The game really needs some serious tweaking, as the controls are awkward, and it's really hard to aim. instead of constantly moving, and only being able to rotate, why not lay the controls out like this:
Up: Move forward
Down: Move backwards
Right: Turn Right
Left: Turn Left
The rest of the controls are fine, but as other reviewers have stated, the enemies are too hard to kill, and the play area is much too small.
Overall, this game has potential, but otherwise it's a waste of time.
