Very cool visuals. The lighting effects and the post-processing adds a lot to the game. The menu is very fun to look at, and ties in to the theme of the game.
The audio is serviceable I would say, but the first time I hear the sirens from an alerted scientist, I was a little scared lol.
On the gameplay side, I found the game to be a bit too confusing. Even when the ultimate objective is given from the get-go, it was not immediately clear to me what I was supposed to be doing to reach my goal.The game kinda devolves into me just wandering around looking for points of interest, which there weren't many. Combined that with the slow starting movement speed, it becomes a bit tedious to play.
With some more balancing and polishing, it could become a better experience, I do like the stealth genre in general.
