At first I thought that the gas would spread and that area would be "deadzone" but seemed that I could go back, so that was fun to be able to explore more. At first it was very laggy and hard to play, went too quick I thought. But then I read your comment and lower the settings and went muuch smoother and I also scolled to get more of a 3rd person view and went much easier.
I mange to get a 42k score so happy with that. Is there any ending or endgoal?
