Great game, interesting stories and puzzles but I have one complaint. The energy cost for stories is increasing with my level. So if I want to finish the offered stories I use up all my energy and time on them. I tried an old story I had done before and the energy costs were much higher. I want to finish the main story but at this rate I never will. When I have to spend several hundred thousand energy to finish a hard story level over several days the game becomes less fun.
