I noticed that some of you guys are very good at the game and earned the diamond trophy on your 2nd or 3rd time through. So, I just pushed an update adding a new hard mode. As long as you have earned the gold trophy or better you can start a new game file in "Rock Hard Mode" and that difficulty should be more suitable to your skill level.
I also made a few minor balance tweaks to the normal difficulty and spread out the amount of tokens you earn so you get more for playing in hard mode.
Appreciate the love guys! Keep the feedback coming on the discussion forum.
