This one was really great! I was pleasantly surprised by the number and variety of puzzles and how intuitive the mechanics were. Details like the block turning yellow to let you know it will disappear when you place your next show a high degree of polish. The atmosphere was great as well, the dingy environment combined with the haunting music gave off a great sense of loneliness. The one area I would say is lacking is the narrative. It gives a very brief explanation in the description of the game page, but it would be cool to learn more about the prison, the attack that led to this destruction, and the character's origin along the way. Overall, fantastic job!
