Pretty unique game idea. The realization needs a bit more work. Perhaps you could try not killing the player instantly when moving into the fov of the enemy.

I got it! I really like this one, position really matters and its more like a puzzle game than a shooter game. Stealth puzzle? You should definitely keep working on this!

Definitely a neat concept, but I can't get more than 30 sec in without it bugging out and killing me. I was pleasantly surprised at how cool and unique the main mechanic was.

I do love how the gameplay inspires you to think a lot more about positioning, and it seemed to work well with me. I will say one thing that caught me was the fact that the enemies could 'see' through the walls.

Perhaps one way you could rectify that is, when the player moves into an enemy's line of sight, have a raycast check whether or not there is an obstacle in the way. 

interesting game-play idea. It could use some work though.

I keep dying for no reason after killing the first enemy (there are no enemies near me when I die). A nice concept otherwise.
