For what it sets itself out to be, an 80's arcade-style FPS, it does its job perfectly! The endless formless labyrinths of death that you'll find here remind me of Berzerk, albeit definitely way less brutal.

The only thing that actually bugged me was that there was only one rather short song on loop. It's not a bad tune, but it does overstay its welcome IMO. Other than that there's nothing I could really pick at. 

Fun!
