This game is so calm and peaceful, and I think it really works with the theme! It's nice to just wander around and find your way around the maze, even if the backtracking is a bit time-consuming it works a lot better with the peacefulness of the music, so that was a good choice.
One thing I think would've made it a big impact would've been shadows with the lighting of the cubes! I think it would've had a really nice effect if that could've been implemented, its definitely something I wanted if I had had time in my game.
All in all, well done!
