The game is well made. However, there are a few issues. Firstly I never knew how to swap weapons. Consider having controls in the game description if not directly in the game itself. Secondly, I found it too easy. Consider having faster or more enemies. Alternatively, force player to make their own difficulty by having a combo system or having your health tick down unless you attack enemies.

Its kinda a run from side to side in a circle simulator.

I guess running backwards and shooting is what I do already in survival games so I'm a little more critical about the theme but still good effort. Standing against the wall and picking them off almost got me surprise attacked so that was interesting.
