Have been playing this game for almost 5 yrs now. Originally gave it 5 stars, was fun, a good time killer, and was a good balance of difficult levels and easy. Having said that, now whatever update the did in my mind has changed the game for the worse. It feels like any time you go on a run of levels it seems right away a hard, super hard, or challenge level (the dumbest thing they thought of) happens very quickly. It's almost like the algorithm they use wants you to fail. Game is annoying now.
