This game was so cool! The map was clear and navigable, and the graphics and sound design were equally awesome. The controls were just too high a barrier of entry for me though, and restarting the game completely upon death made it too difficult to complete.
The slow turn speed and clunky strafing made it really difficult for me to really get a grasp of my surroundings, so I didn't feel like I was scouting and gathering intel for a stealthy escape. It felt more like I was hiding.
I feel these controls would be better for a horror game, as opposed to a stealth game.
Aside from that though, i thought the game in concept and design was great :)
