Usually I´d say this is a really great game, but with the time it started to lagg so hard, that playing wasnt real funny anymore. Try to fix that ( if u want to keep on working on this game) and I´d rate it 5/5, like this 3/5 only.
Just to tell you, if the geek comes into the air and knocks on the ground afterwards, you can easily wait some seconds and get 2 possibilitys :
1) You got enough creeps on the way and the geek flies up again
2) The geek is near enough to earth to easily land a Hell Raiser.
So where is the problem?
