When I began playing the game my energy level would only climb to I think it was 120 maybe then I used purple diamonds to purchase two energy bars which raised climbing level to go to 150 each time so then I purchased the three energy bars with diamonds thinking it would raise my ability to store a larger amount of energy but it didn’t work! Is there a way to raise the stored energy level beyond 150?

My energy level stops at 150 is there a way to make this go higher?
