Prizes, coins, money

I really like this game and have all the characters including the three rare ones so far. I was really excited to BUY the dreamland stage because i thought there were different challenges. But no, its just the same thing and same score to beat. If that were the case, couldnt we have just unlocked it with our coins instead of paying real money for it??? I have thousands of coins now because there are no more characters for me to play the prize game so i let it collect. If we have to pay for the other stages can you at least make the challenges relevant to that stage? Like for instance the underwater one, instead of the same plants that throw out fireballs you could replace them with octopi that shoot ink for all i care. I just want to pay for something thats not exactly the same as what ive already been playing. Please dont let this app die out like the rest that were "cool" in the beggining and then get boring after some time. Im tirednof looking for new games to play. Thank you
