I've played my share of puzzle games, and I gotta say this quickly became one of my favorites. Simple but pleasant graphics, easy to understand mechanics, and short but satisfying puzzles. So thanks for making such a lovely little game!
One thing I will say is I had to stop at level 27 due to frustration. I just couldn't get the timing down and kept accidentally pressing the button... not sure if I'm missing something. Otherwise I had a great time!
