I'm not going to complain about the controls. I will claim that it just takes too long to kill your enemies. There didn't seem to be a lot of difference in terms of the weapons bringing more damage. It does seem like the design is fairly good. I just don't understand how there's a lack of mobility. I thought the level where you couldn't kill anyone was hard!
I don't mean to complain, but it could be better in many ways. The best thing is probably how you have a lot of lives. It takes awhile to get used to the mouse movement. This isn't something I would recommend. It was pretty mediocre.
