OctoWalk

OctoWalk is a port of the physical limb controller from the game Octodad: Dadliest Catch. No longer can you use WASD to move. Instead, you control each of your limbs separately using different on-screen keybinds.

(Almost) all normal Minecraft functionality persists: you can walk, build, and fight. However, you are unable to jump, because octopuses cannot jump (duh). Swimming and climbing are still a WIP.

I would be very surprised if someone managed to beat the game with this mod.
