Thanks! I think I see what you mean.
Please note though that the Box2D port I used here is of ‘Box2D Lite’, which is, as far as I can figure out, the renamed version of a really old version of Box2D (close to when the original author first presented it to the world) – this was likely done to be easier to port of systems like the Playdate, but it does make a lot of the tutorials out there not quite applicable to this version. For example, there aren’t different joint-types, it’s all done through the same joint-class. – It’s simple enough that you can just pick it up if you’re familiar with the Playdate C-API though!
