I absolutely ADORE the lore, the challenges, the little extra dialogue; IT'S BEAUTIFUL. Everything ties together, even if you can't tell at first. It's amazing how you also get a bit of character development on the parents, even though you don't actually interact with them.
But even though I praise your work here, I also can't quite figure out the code in the parcel. I got the knife, I opened it, I had the grey key, the power was on, and I read the father's note in the floorboards.
Yet I can't seem to make out the code. Maybe to a system that tells you which numbers are right and in the right places, or maybe just make the code a tad bit easier..
