Really like the game but hate the ad breaks. They ultimately knock me out of the game when they start coming faster It would be nice to be given the option to remove them. The game operation itself is smooth and well-designed. The sound of the blocks is well-done. No annoying music, or garish colors, or supposedly-cute "helpers" - for which I give thanks, lol.

Beautiful game with satisfying sound effects. It feels so close to playing a game with physical blocks. The game is played by moving blocks to make a path to free the key from the box, within a set number of moves. For me it's challenging and fun, but the game is so pretty, my guess is that even people who are really good at picturing the moves would still find it fun and relaxing. Definitely worth a try.
