A close friend of mine is making a playable-spider-girl-based game.
I'm in the process of programming a procedural spider walk for it: https://youtu.be/oeBFCxbtwXM
The spider body is placeholder, it will become a drider. The plan is to make the legs able to seek and grip on arbitrary 3d geometry, including flailing when no good purchase is available, and allow the spider to traverse on any surface.
Edit: I am also chronically ill but slowly finding stability, don't hold your breath for this to come out.
