Very clever puzzle game! Completed all the 10 levels. Level 9 took me a while to solve it!
Of course, there's room for improvement. Adding sfx, music, and more levels would greatly improve the feel of your game.
Also, another friendly tip: If you want people rate and review your game, reply the comments they made on your game. If not, other people may probably avoid rating and reviewing your game.
Great job! Congratulations!
