Make badges worth something...
Game is good fun, but each mystery is solved half way through. There is no reason to get max stars on each scene because the badge awarded has no value. It would make more sense to be able to use those badges to trade for gems or energy. Otherwise its pointless. The gems are very pricey. If that were changed, I would rate much higher.
