The game has potential if designers would limit the items to clear or lower their energy requirement. Also, limit the ads or shorten the ads to 5 seconds as there are too many ads at 25 - 30 sec per ad - too long. Events have too many items to clear to get to goal, however, that wouldn't be an issue if changes above were considered. I enjoyed the game at the beginning but grew tired of ads and frustrated about the high use of energy. I recommend passing on this game - sadly.
