Fun in until...
The levels are ok. Game didn't move pass level 36, played it several times and passed and the next level would not unlock. You don't have to spend money to play or get better equipment, the amount of coins you get by winning will be enough to advance. I do wish the game play was a little more fluid. Every time you pass a level you have to view an ad (5 sec),and go through the whole start menu again and again after each level. Hoping they will update soon and open up more levels.
