Tower Color APK 1.7.4

5 stars: I'm on level 1396, I have 19596 coins, I own 36/45 of the skins. How do I get the last 9 skins???? Adding to this- I have paid twice to remove the ads but I'm still seeing ads on just about every freaking level. Now I'm on level approx. 2900.
4 stars: Very glad they got rid of the constant ads running along the bottom which caused it to keep freezing up. Love this game, have played greater than 13,000 levels and just keep coming back for more. But it needs some small perks/challenges such as tracking time maybe or number of wins? Also have no idea what the gems are for.
3 stars: Much is excellent. Love the graphics, physics is well done. But the gameplay is repetitive and lacks goals. Percentage done shown at the top is too small to read, should be twice the size. I paid for ad free and it is ad free except for optional 3-more-balls so that's fair. I'm still enjoying it at level 70.
3 stars: Too many ads, and price of ad free version is too high. I will pay a couple dollars for ad removal in a game I like (and I like this game) but $6 is not worth it. Very fun game but way too many ads. An ad plays after basically every level. Levels can be quick and ads can be long. Almost more time in ads than in game :( Change ad frequency and you get my 5*, drop your price and you get my $$. Great game though, very fun!! Addictive!!
2 stars: The game is fun but the Ads are ridiculous! One after every single level is excessive! And paying $4 to remove them is also
