Summary
Change climbing challenge to give smaller bonuses at each checkpoint.
Core concept
Instead of having to reach the top, what if every checkpoint gave you something for accomplishing it since many people may not be able to for one reason or another (acrophobia, motion sickness, skill, etc). Like the first checkpoint could let you climb only wood, then next checkpoint lets you climb ground slopes, then next checkpoint is stone, etc. Or even something like limited climbing stamina that gets extended with each checkpoint.
Personal twist (optional)
I don’t think I’ll ever be able to complete it legitimately due to the heights getting to me so I had to have a braver friend Uber me to the top via teleport but the climbing mechanic is a lot of fun and I’d hate for others like me to miss out.
