2dFish

2dFish is a 2D esoteric programming language made by User:WhoeverKnew123 for fun.

Syntax

The syntax is the same as deadfish most of the time. 2dFish also has befunge-like arrows! The arrows are up: ^ down: v left: \ and right: /

/iisv
    /isv
   @oii\

The program above this text outputs 27 to the console. (@ is the symbol to terminate program.)

Computational class

Not turing-complete. No flow control or anything. It's just deadfish in 2d.
