Answer: ECTOPLASMIC

by Jakob Weisblat

This puzzle involves walking around ⊥IW to locations that have an X on the ground. First, we must figure out which scene with an X fits each instruction. Then, we can follow the instructions, starting from the X, and draw lines to spell out a letter on the ground, viewed from the perspective of the bottom-right corner of the screen.

Author’s Notes

This puzzle was inspired by (Athletics meta spoilers) the title constraint of having to start with an X, imposed by the Athletics round supermeta.
