I went through block B.
The game is fun. You really nailed the atmosphere. I think the lightning is really perfect where your flashlight is turned off. I like the kickback effect when shooting (actually it's more than kickback, like you're falling and get back up?) and the overall immersive approach with the animation for taking your flashlight or even the slow movement, which feels adequate here as by the time it could become annoying you already completed the game. The puzzle was cool and appropriate for the context, the game isn't hard but difficulty is above trivial which is nice.
It's a bit weird that you need to be close to an enemy to be able to shoot him. Also lightning is alright yet a bit weird when the flashlight is on because of the central black circle.
The game is cool, thanks for sharing.
