I was thinking about making the climb shorter - instead of 4 levels cut it down to 2 first ones(with slightly editing the 2nd stage), so it's quite fast n' easy minigame with 2:30 countdown
and also adding a 2 min countdown to bhop.
+afaik if i wanted to change the climb to something different than glass, I'd have to make a 2nd set of the same textures used in climb, but made out of a different material ex. concrete.
