My main point of feedback here is how relaxing the environment. I absolutely love the feel of this game. Puzzle design throughout the beginning was really good, but i started to get confused at level 5. I was unsure of how to use the boxes. My mind kept going to the classic "Portal" put-the-box-on-the-button solution, but couldn't get the to work, either because moving them was imprecise, or because buttons didn't work like that. If they're not supposed to work like that, I'd suggest making the buttons a switch, or something similar. Those minor points aside, this was a really well done game, and i enjoyed all 4.5 levels is played! :) Great job!
