Cool! I'm gonna try it out! Were you inspired by BoBoGram in the making of this puzzle?
Also, I'm reading that BoBoGram was inspired by Abdec: https://letibus.itch.io/abdec, another pencil and paper "discover the rules" puzzle!
Nope, Bobogram was way after (and it didn't consciously influence any updates). I was inspired by ABDEC's predecessor LOK -- which just came out on Steam today! Big fan of ABDEC as well, though I regretfully looked up answers on two puzzles.
