The game itself is incredibly cute and engaging. Unfortunately, pop-ups to buy this or watch an add for that happen approximately every 3 to 5 seconds, making getting to the game to actually play it too difficult. Uninstalled.

bought a pack by mistake, and the company won't refund at all. I bought a pack by mistake. I have emailed google about this. Do not buy or play this game filled with ads

I want to like this game. I do. sadly the slow movement. (slide you finger all the way across the screen and move a couple of millimeters at snails pace) and the constant demands to buy this that and the other and/or watch an ad make it impossible to judge the game on gameplay itself. I'm not sinking money into a game if I dont know if I will enjoy it and I'm not watching a million ads to play. that's tv without any good programmes. I can do that for free on YouTube.
