Sort of annoying
Found it annoying trying to first figure out I could only select certain blocks even though huge chunks of same-color blocks were next to each other. Also found it annoying wasting time seeing the animation over and over with the blocks smashing together and making that shattering noise (which got VERY annoying after a while). The amount of time watching those blocks smash together starts to add up, and makes you feel like you're getting robbed.
