I'm enjoying it. The puzzles are difficult but don't try and do one area in one go, you will have to learn about how to solve the puzzles in different areas and come back. You literally have to explore the whole island before you learn all the rules to the puzzles. Invisible walls? The are wall to stop you going of the edge but that's about it and why is jump relevant to a puzzle game.
This game is extremely well made and beautiful to look at. After pumping about 20 hours I'm yet to see one bug.
Not everybody is going to like it but do you play many puzzle games because I'm not sure what you were expecting.
