It's OK
Loved it, I'm a sucker for retro-like games, but I was very bothered by the controls. if you use the mouse to aim you should have at least the option to use wsad as alternative directional buttons. Some of us use laptops... aiming with the left hand is a horrid task -.- that's really why I gave you a 5 overall.
Still, good work! Hope your next game has more laptop-friendly controls.
