1. Like a true heretic, you need to explore counterclockwise and go to the right bridge first. then you will be able to have exactly 0 coins after opening the left bridge. probably that's the condition to reproduce it.
3. Ok, probably I wasn't paying attention initially, and then Got overly suspicious after finding the bug 1. like... 20. why 20? that's a double of 10. must be some kind of heresy.
Thanks for the duck, I was really happy to find it finally.
it's impressive that you've managed to participate an complete a game with lack of time and crashing pc. that's the level of dedication required to thrive in gamedev.
