Too expensive if you want to keep advancing. – Balloon Crush Review

Unless you want to buy more “darts” you always go back to level one if you don’t pass a level (and I just got to 40!!) My $8 lasted me only about 2 hours worth of game play. You should at least be able to stay at your level! Very fun but no good if you can’t afford to keep moving up.
