It was fun to run around blasting people and kicking in doors. The music was fun though I'm not sure you have the rights to use it haha.
Visuals are pretty baren and the mouse sensitivity was unusually high.
The gameplay could use some variation. I found myself not really entering rooms anymore and just moving around outside after kicking in the door and just shuffling around until I could see an enemy and shoot them and only then entering once most enemies were already dead.
