I really love this game! First off, I am in love with the Gameboy-esque visuals and sound effects; the graphics and animations are very simple but have a lot of charm. The music is subtle but great and I feel that it adds a lot to the relaxing puzzle-solving contained within the game. The core concept itself is also very creative; when playing your game, it feels a bit like I am playing a Tetris/platformer hybrid. I also love the attention to detail; I was about 10 minutes in before I knew you could get crushed by moving tiles. The one critique I have is I am not a big fan of the movement, but I saw the reasoning in the comments under your game, so I completely understand why they are this way. Overall though, you did a great job, and I know I would be super excited to see a full release!
