Great game, finished the demo. Visuals look great.
Just some points, sometimes it's difficult to grab on to the rope, the character just slides to some crazy areas if its close to the ground. Also its quite difficult to move around, the ledge grab from the rope might be better if it was a tad bigger. The character doesn't grab the ledge unless its aimed the rope exactly at the corner. Pretty much had to be pixel perfect.
All in all a great game, other than the difficulty maneuvering around, I love the visuals and atmosphere. Looking forward to playing more of it. Gave a little tip for your troubles =)
