Pay walling

The game is fun and pretty straightforward, my problem is that it pay walls you. Meaning that after you complete a puzzle you get coins, some additional coins if you got the bonus tile the correct color. But even if you get a perfect score on every puzzle, by the time you finish the third set you wont have enough coins to buy the next set, leaving you only to buy coins with money to progress or just play the alternative "Time Attack" mode which really isnt that fun.
