Well, to be honest the game is quite fun. I do play the games many times in one go at first but not anymore. It just because the other element of the game makes me want to write this 1 star comment. The sticker collection is really frustrating. Have spent much time and effort but always get duplicate, again and again. Annoying right? I suggest that everytime player get the same sticker, it increases the chance to get missing sticker by some percentage
