I love stealth games, and yours doesn't disappoint! I'm saving this one to replay in the future. It looks absolutely stunning, you picked your assets well, and the bush stealth mechanic is genius. Also, I love that you implemented difficulty levels and graphic qualities. I actually lagged a lot on high quality, so it was nice to have to option to lower it down to something I could work with.
I had one issue alone. The camera was waaaay too sensitive, to the point I didn't even know I twitched my mouse, that I found myself facing backwards, and towards the ground/sky, confused as to why I was getting no closer to my destination. It was funny in a way, until it became a little irritating.
Anyway, all in all, it's still an awesome game!
