Surprised at the depth of the mechanics! Seems very simple at first, and the complication of objects blocking your view dawned on me very naturally. I did get pretty stuck at maybe the 3rd puzzle with the rock formation and didn't have time to finish. I'd say the one issue I had was with the visual language for clicking stuff. I kept forgetting if I should left or right click. It's a small gripe however for an otherwise amazing experience! Great job.
