This certainly qualifies as So Bad It’s Good.
If you want a little bit of constructive criticism, allowing WASD controls (along with the existing arrow button controls) would make the gameplay experience a bit less uncomfortable, considering that spacebar is used to jump and the player’s right hand would probably be a bit preoccupied using their mouse to aim/shoot.
Anywho, control discomfort aside, this right here is some definitive SBIG-ness.
