I like the vaulting solution, seems like it might solve a lot of climbing problems. A physics rig demo scene with extra dude, and a bit of 'gravy'?. You've used the same system in multiple Jams, it'd be nice to see it evolve.
That's the goal! Really what I want is to keep working toward a rig and systems that give me everything I need to make a game like Vertigo2. With my own story and characters and world, of course, and much smaller scale. I love that game.
