Great concept. I look forward to seeing it grow. I recommend increasing the contrast between the text and the background color on the cards. Make the background color for the text boxes much darker so it's easier to read.
So most of the ores are to be given to dudes who create wonderful things to help build the city - except for diamonds and rubies, which are to be given to the only female who does nothing for the city and is rude. Doesn't sound like much of a utopia to me...
Day 1: THIS ROCKS! I am not going to have a life anymore! .................................................. Day 2: Yeah!

Hmmm... this is kind of the same .................................................. Day 4: Meh...
