Ads galore, and greed.
Fun gameplay. Greedy devs. The gameplay is easy and simple, until the greed kicks in. Certain levels are nearly impossible without an extra branch, costing coins or an ad. Every level or two, "Take a break!" and there is just another ad. And than the cost to remove ads. 13.99? I'm not playing this so much, so why 13.99 to remove ads? Some players even reported ads after paying. This is purely greed, with the amount of ads and price to remove them. 3 star gameplay and 1 star fun. 2 stars total.
