Thanks for investing so much time in my odd little game! :-) It can be completed in about 30mins if you know which enemies hold the Dragon Stones. Sorry about the awkward UI, it grew organically and is difficult to change; my next iteration of this engine will have a completely redesigned UI. The great thing about the DC jam is that I'm getting so much useful feedback from people who really like playing this type of game. Look forward to trying out Louvre Heist.
PS Glad you liked the 'so-real-you-could-almost-be-there' 1980s graphics, lol.
