Interesting concept . I was surprised that the turrets can aim in a complete darkness! The 1st wave of the 3rd level was a great challenge, otherwise it was too easy.

The idea of trading power for visibility is really neat, I just wish it mattered more. As is, you don't really need to see what is going on. Still, fun little game.

Yo this is really good! I like the use of limitation here and the game play loop is pretty satisfying! My only small gripe would be the placement system. It could not figure out what it considers an invalid space and what it considers a valid one. Other than that this is awesome!
