This game is unbelievably addicting. In sonar mode, your gun shoots sonar balls that realistically bounce off walls and ceilings, illuminating the surrounding area where it touches.  But to shoot bullets, you have to exit sonar mode completely, making you nearly completely blind as you fire at enemies. The result is an fantastically smooth experience of flowing into rooms, firing sonar at corners, and then memorizing what you see as you rapidly switch back and forth between lethal mode and sonar mode.  You feel like an expert operator becoming one with the pitch darkness.

Fantastic work by the devs!  This is definitely a game I would have paid money for.  What a fantastic concept.

The game made me think there was going to be a jumpscare around every corner Very cool 4/5
