I think we can all agree that vanilla Minecraft has very simplistic movement. Wouldn't it be great if that changed?
This is a request for a 1.12.2 mod that does just that. I have a few suggestions as to where to start, so see below.
A) Crawling and sliding. The most simple addition in theory, I think it'd feel really good if you could hold down a button to lay on your stomach and crawl through 1x1 spaces. Or, if you're sprinting, hold down the button to slide and then release to keep your speed up!
Wall running and wall jumping. There's already a wall jump mod, but I want to take it a step beyond. Imagine running along a wall, then jumping forward and grabbing a ledge to pull yourself up!
C) Swinging. Now this one is something I've never see anyone bring up. Imagine if you could grab certain narrow blocks(like fence poles) and use them to swing like an acrobat. When paired with something like Dynamic Trees it would make forests and jungles lots of fun to navigate, especially if you were to add non-static vines that you could use to swing on.
Those are my ideas so far. What do you guys think?
