Earning gems and use of energy

Offer the challenges within the games to earn gems not from other app.

In addition, use of coin to buy energy should be added and be reasonable given that the players spent 10 life per game.

Make the 160 energy last longer by reducing the current 30 energy to play a regular crime scene.

Earning star in any given scene is long and takes all of the 160 energy we start with!
