⚶

⚶ (pronounced Vesta) is a tree-based esolang made by Ϫ (talk).

Before a ⚶ program has been run, the tree has one node, 0:0. The pointer starts at 0:0. Any point on the tree is defined as [generation]:[ordinal]. For example, say that there is a tree defined as such:

       @
     /   \
   @       $
  / \     / \
 @   %   @   @

If the pointer is at the point at the far bottom-midleft [the %], then the pointer's location is the 2nd generation and the 1st ordinal. If it's at the middle-right [the $] then it is in the 1st generation and the 1st ordinal. The pointer has a memory cell that can contain one number.

Commands

ᔹ	Go down the tree, favoring going left if possible.
ᔶ	Like ᔹ, except for going right.
ᒬ	Create a node to this node's down-left. If there is already a node there, push it further down after creation.
ᒭ	Create a node to this node's down-right. If there is already a node there, push it further down after creation.
ᑍ	Go up the tree.
ᐰ	Go up the tree, destroying the current node and anything after it.
ᖃ	Subtract the current ordinal from the memory cell's value.
ᖁ	Add the current ordinal to the memory cell's value.
ᖒ	Output the memory cell's value as ASCII.
