Mini Creations | Climbing - Only One Command

Hello! Today, I've created yet again a very small creation, but I think it should be in the game! This creation allows the player to climb up certain blocks!

Click here for the command!

Tutorial:
To climb a block (this can be either: a tree log, or cobblestone), simply stand next to it and sneak. You will
begin to rise up the block. If you at some point let go of sneak, you will fall back down the block! You can
also cling to the bottom of these blocks as well, just by sneaking underneath them!
