Thanks for playing and the feedback! I really appreciate it, especially how to replicate the music bug (I had seen it but hadn't reproduced it yet).
I hadn't really thought of starting the player at the CURRENT crank position honestly. The movement should be 1-1 so 1 rotation of the crank is 1 rotation of the player, but I think that there's a little bit of crank "drift" over time as well (just a limitation of the hardware I think?), so sometimes the crank movement doesn't correlate 1-1 all the time, but it should be fairly close. I can see how starting the player at the crank's position could be helpful, I'll have to look into that.
I'm working on another Playdate game at the moment, but I'll definitely look at an update to PogoArc at some point.
