Cool if you like 3D things
3D lines, that is. It was fun for about thirty seconds, then it gets old, but if you had objectives ( :D ), like facing the guy in a perfect angle, it would put a little more meaning into the game--you'd get less blammage, more reviewers whose opinions you cared about . . . but since the title tells you what is included in this game, you shouldn't get a bad grade--er, blammed.
Overall, this is more of a thing for 3D-lovers. I suspect you were bored while making this.
PS I gave sound a 5 because my volume was off (at least I think so).
