Too many ads and I was surprised by the high coin cost to play each level. I guess I wasn't expecting it to increase so fast I mean island one 500 coins to play each level then on island 2 it went to 1500 coins to island 3 is now 2500 to play each level that's a lot of coins! And game tends to freeze up often . I really enjoy playing this game but I think it could Use some work. (About the coins I figured and increase which is normal like say 500, 1,000 or 1200, then maybe like 2,000) gradually
