I played and liked! All the animations make it feel very polished and consistent throughout, and the gameplay is an interesting twist on match-threes! As mentioned before, difficulty could increase a good bit quicker to make for a good challenge. Other than that I'd really like an indicator of which column is currently selected to shuffle (It really shouldn't be necessary, but I occasionally confused the column I had selected with another one, and it would probably go very well hand in hand with the otherwise flawless UI).
