Neat little game. But as others have said, it's a bit low on the looping aspect. Lack of music and an inability to change the settings at the pause menu is a bit unfortunate as well. Another thing that was bugging me was the push mechanic only going in one direction; it seems like an unnecessary limitation that makes puzzle-solving more annoying than it needed to be. On the other hand, I can see very interesting puzzles built around that limitation. Beyond that, you have a solid foundation for an excellent puzzle platformer game.
