This game is designed to waste your time, get you upset and push you to spend money and do absolutely nothing with it. The more difficult it gets, the more pointless everything becomes. You nees rediculous amounts of goods and energy in order to do 1% of the task at hand. The rewards for additional challenges are not worth the time. It makes you keep coming back, checking if your energy levels have gone up - you become an addict. You also become anxious and frustrated while playing. Not worth it
