Looks like you worked it out! Happy questing and feel free to message me here if you get stuck again.
Thanks, but I'm still stuck: having exactly the same problem as st-fisch, below.
Did you use the PD crank?
Ah. Yes. I seem to have forgotten about one of the Playdate's main features. Thanks.
Happy questing!
