This isn't something that was hard, but it is very fun to use and was very fun to create.
I made a script which runs on the client which allows the user to jump from vertical or nearly vertical walls and objects.
The script works with FE because of how the humanoid replicates to the server. This means the animations will play on the server, and the character's position will be fine when jumping from walls.
The script works by casting rays from the local character's torso to find a near wall. It picks the closest object, and if it's within the max distance you do a wall jump.
