2D languages FTW! Although writing loops and branches using goto instructions instead of the 2D structure is not fun.

The fish swims downward along the code, using conditional gotos to skip things depending on what divides the accumulator.

I believe this meets the spec: whatever newlines are removed, the fish always hits the initial `v` (the only direction-changing instruction present), so the fish always swims downwards in the first column. Thus deleting a newline has the effect of simply removing the next character from the fish's path, and I don't think you can remove any of the characters without changing the output.
