I love it! And I have one comment to the Devs: Would it be possible to add to the in game display; how many gems you have accumulated in your current run alone? Some challenges requires you to only take a specific amount of gems but the in game display only shows you your grand total of gems all run included so you have to get crafty and mentally calculate your grand total of gems plus your specific amount of required gems to know when to stop taking gems for every run and that's annoying.
