I have reached what looks like the final constellation and can no longer get new ones as I win stars completing levels on an island. According to the "island progress" chart, I still have 500 or so levels to complete. As the levels get harder, it's even more necessary to make use of stars for coins and other rewards. What gives? Also, why don't you allow purchase of special gems? I have thousands of the purple and blue ones, which don't mean much, but it's almost impossible to win moons or green teardrops (leaves?). I'd happily pay for some or buy coins with which to buy them that way, if that was an option. It's boring to go back to the easy levels and reply them over and over. just to get these rare gems.
