Walking into a wall prevents jumping
When you walk into a wall, you can't jump. It may seem trivial, but it allows you to practice acrobatics insanely fast - just keep banging the jump key as fast as your fingers can go.

This is probably the same bug that keeps trapping the player character in trees and toadstools. If the PC moves too close to a tree or walks into a clump of toadstools, the PC may become stuck, unable to jump. The only way to free the PC and continue the game is to use "coc [cellname]" in the console.
