Thank you! I haven't gotten far with the background as I planned to have it scale to the puzzle, but this may be a little too complex for me. I am working on the rng a bit. Bioshock's hacking game was an inspiration, and I also didn't want to hide them the way BS1 does. The puzzle was intended to have multiple grids as it became more challenging, but this is still in planning. I hope I can get this working one day soon.
