Shades is a great game, an interesting spin on 2048-type games, with Tetris-style mechanics. The only complaint I have is that the column in which blocks can appear from is completely random. When things are getting hectic at the top, you dont stand a chance because your fingers will not be able to move the block over in time. This means you have to keep all columns pretty flat across the playfield, which complete negates the entire strategy of the game. Still pretty darn good though!
