Very Good
This is a very good game. I also really like the fact that the guns aren't used to deal damage like with most shooters, but are instead used to propel the other enemies out of the ring. This is an incredible strategy game. The only real problem I have is just like what pivotman123455 said, it's like walking on a marble floor covered with pam. If you're on the edge of something, sometimes you'll fall off if you aren't careful.
