The beauty of this game is that is really fun and challenging. Also, this game is 100% ads and micro-transaction free. However, only the first levels are free. If you want to complete all the levels, you’ll need to purchase the Pro version. If you really like this game, I strongly suggest you to buy the game to encourage the developer to make more games like this one. This game cost less than a coffee and will grant your hours of entertainment.
