I think this game's biggest success is its accomplished visual style and sense of humor. The stage-like screen and some textures visual similarity to yarn create resemblance with a puppet or cardboard cutouts theatre show. This resemblance is also complemented by the shaky effect after each 'tap' and a farcical victory sound effect. The overall impression is that of a street farce or a slapstick comedy, which, in my opinion, is a quite refreshing and interesting style for a 'clicker' game.
With that said, however, I have to say that this game also suffers from most of the other 'idle' games drawbacks, like repeatability, lack of content to fill in seemingly endless playing time, and, most of all - gameplay mechanics simplicity, which results in effectively gripping, but meaningless addiction.
