YEAH!
Very well designed, with some great stealth puzzles which were tricky but fair. Showing the player the direction the enemies were going to face in from every point is a brilliant idea, and really allows for thoughtful and considered play, although I still managed to mess up frequently haha
I really liked the whiteboard-style graphics, and felt that they were very well suited to the gameplay as the simple presentation made it very easy to read what was happening at a glance. I've always loved the Rayman "yeah" sound effect too :)
