Beautifully executed. My only gripe, is the jump height is not variable depending on how long I'm holding it. I wish it had that added in, because at times not being able to control how high I'm jumping threw me off.
However, fantastic mechanics, unique in the aspect of the eye sight. I found that interesting, and it had a tactile nature to it. As some of the same mobs have different eye sights. The sneak was implemented flawlessly. I liked how the bushes added variation in how to approach the challenges.
