I've never been too good at puzzle games, but this one played in such a way that not only was I able to work out the mechanics of it and understand what I needed to do early on, but it also introduces new puzzles and mechanics to you through the gameplay for later use. The little sounds the blocks made when rolling was a really nice touch, and both the background music, and the simplistic aesthetic to the game went together really nicely and complimented each other.
One critique I have is the camera controls. Whenever I clicked A or D, the camera would pan for a short period of time before stopping, and I could not stop it while I was moving. Sometimes the responses were delayed as well, meaning sometimes I would lose control of the camera, or get sort of disoriented. The "It's a Trap" level also gave me some trouble, as I would stop the cube mid-air beside the orange block in the center, and then the game would get stuck and I would have to restart, as it wouldn't give me any more cubes.
Aside from that, I enjoyed the game, and I'm very impressed that you put all this together in a team of one within the span of a week!
