A really nice game.
Just a few problems i had with it:
-you can solve some puzzles purely by accident leaving a sour taste behind. I still don't know the mechanic behind the "pyramid" puzzle 4, but i can easily solve it.
-puzzle 7 can be frustrating, especially if you can't interpret the hint on the wall. I couldn't so this hint was actually more misleading then anything else, because i constantly searched for some other meaning then the hint that was already given in the description
-the wheel puzzles take to long. either let us spin multiple sections at once or increase the speed at which we are able to press the button
