Is this intended to be possible? I discovered that a player can jump great heights by jumping, putting a crate below his/her feet and then jumping again. if it's done right, you can do it theoretically infinitely, if it weren't for the vertical boundary. I kind of like it as it's really useful for escaping holes in the thawing plains without wasting a lot of crates, but I'm not sure if it's supposed to be a feature or not.
EDIT: Apparently there's already a thread for this. Sorry, didn't see it.
