Haha, cool, unofficial record holder! Anyway, yeah, hard to say whether changes like pre-grabbing would feel right until trying them, also thought about having hard to grip holds which are indicated by haptic feedback, at the end of the day maybe simple is best though, haha. On the other extreme I have been planning to try a purely physics based vr locomotion system some point, where you react to physics and only your head and hands have collisions, so then climbing would not require coding, but be just putting your hands on top of holds and pulling yourself up! perhaps physics glitches would be too common and nauseating though, only one way to find out, ill let you know how it goes!
