Interesting.
This game has got possibilities.
But the big thing I disliked was there was no hotkeys for the different ammunition!
To be able to swap between Freeze to Rifle and then back to Freeze would make this game much more enjoyable and playable when half a dozen Metalheads come raining down at you.
Some different sounds for the three different ammunitions, like perhaps shotgun like sounds for the normal shots, a more rapid sound for the Rifle, and perhaps some kind of lazerish sound for the Freeze?
