Overall, this could be a great game, but it's too buggy. The MANY ads keep crashing the game, and when you re-enter the game, it skips the level you were on and tries to set you on the next highest level. If you click to start on that higher level, the ads crash the game, and each subsequent time you reload the game, it counts the level you never played and tries to up the level again. It's insanity to try to play until the bugs are fixed.
