Very fun puzzle game! I like the take on the loop theme. I wish I could play more!
If you could put in the description that you control the cubes with the arrow keys, that would be nice. It took me a little bit to figure that out. (I kept trying to click it)
Also, you should edit the description to mention reloading for music not just audio. Because my game audio was fine, but I didn't realize there was music until I reloaded the game. (very good music I may add)
