he's probably saying something about the transition between roblox and blockland, where you cant climb a easy-made ladder like you can in roblox. maybe for the next update he could ask telamon how to script climbing ladders like that... but if badspot DID figure out how to make stairs climbable, i think he should be able to figure it out himself.
another idea is, well, you know how JVS automatically comes with events? you could just make a prop that looks, majestically, like a ladder and just put a dang velocity event into it.
