Very incomplete, and controls are less than optimal. As stated in the description there is no ultimate purpose to this game whatsoever besides combating an endless swarm of enemies by spam clicking on them.
I feel that the controls could be better optimized, like moving swap weapons closer to the movement key so that you don't need three hands to play game. On top of that being able to hold down to shoot instead of spamming the mouse would be a whole lot better.
