I played the demo. You get to read the minds of cows on a farm, and after one craps on you, you use telekinesis to throw them around. I like to drop them in the lake, or throw a tractor at them. Then, a farmhand comes out with a shotgun. You get a zapper to kill him that acts like twenty tazers. You have to get his brain stem, and when you get it, his head explodes! After killing some more farmhands with methods of your choice, the cops come by and talk to the wife of the house. You kill the cops, or "inquisitive authorities" as your race calls them, usually by using telekinesis to throw their car at them.
You finish the demo by getting in your saucer and using the death ray, which is a flamethrower mixed with a laser, and blow up the "human dwellings". then the army comes with soldiers, trucks and a tank. Sadly, the demo ends there
At least it was fun!
