High ratings accross the board from me. The concept is precious, the execution is solid, and the hats are tip top.
I was a big fan of your occlusion tech for going between floors (teach me your secrets!) but I did find it occasionally difficult to tell which elements belonged to which floor, because of it. Same goes for sight cones, passing through walls, making me unsure if I was going to get spotted or not.
It's also just a fast game. Maybe a little too fast for my more plodding, methodical style of stealth, but I'm willing to chalk that up to preference. Well done! I hope this game gets the attention it deserves.
