I really enjoyed the art of this one, VERY well done. However, the lack of any real communication led to me guessing what I should be doing. Also, the puzzles were interesting, but easy to overthink, and some were simply just spinning a dial. Was it all either because of bugs or because it wasn't that great of a puzzle? I'm unsure. I did like how it randomized the orientations, however.
Suggestion: Even without dialog, it’s still possible to convey things to the player on what they should be doing. Maybe give an example puzzle or two for the first levels to show the ropes, then leave the player to figure the rest out. A puzzle game should be about logic, NOT guessing until you get it right.
