P.I.C. - Community Competition!

[Shempster]

I have two things to state here -
First - The screens need to be more consistent.  Have either a "Close" button on each, or an "X" in the top right, not both.
Second - To help the engagement of new people, and the Challenge system - How about rewards for helping in challenges?  You can either have the user put up their own gold or diamonds, or each challenge can have a set reward per level if you help with the challenge.  Just an idea.

Thanks
