I love the dark atmosphere of this game, and the idea is well executed. I had some trouble distinguishing the two lighter shades of blue, maybe it would have helped to show the partially satisfied requirements. I still managed to complete 15 orders!
Highlighting or otherwise showing completed requirements is a wonderful idea! As for colours we'll probably tweak them some more to make them more distinguishable. Thank you again for playing (and good job, 15 orders is an admirable result)!
