The art is great, the music is great, the sound effects are on point and the gameplay is fun!
My biggest complain is that most of the time I'm just waiting for the blocks to fall. I would like to have a button to accelerate the game. Or I would like to do additions with the blocks I already had (For example, I had a lot of 6s and 2s, so I would like to combine them to make an 8 and then combine that 8 with another of many 2 I had)
But the game is really good! I really really liked it!
