Overall this is good game not great just good.
The limited weapons are well limiting and are boring, but you plan on fixing that.
Why would a cutting laser especially fully charged have trouble going through the corpse of a already dead zombie to hit the very alive zombie right behind it?
Because of how littered the small levels get pretty soon every zombie you kill makes it much harder to get hits on the remaining zombies. I hope this won't be carried over to the full version.
