This list will grow bigger over time, but I will need your input. Tell me what challenges should be added/removed, if one should be moved from a difficulty level, etc. I will also need your feedback on each of the current ones, and show us your progress through screenshots too!

Challenge number 3 accepted

I actually want to try and do that last challenge

3rd one.
