A lot of potential
Not the best graphics, but I really liked this!
There's a few flawes for it to be perfect imo. I seem to only use the laser, magnet and nuke, since the pulse and shockwave are only good in rare occasions like the minibossthings. Also, maybe the nuke should be fired by using space or something. I often fired them by accident, when holding the mousebutton while changing weapons - but that might just be me who's too stupid to let go of the mouse :o)
Concept was absolutely 10/10
