Just played through from the start, pretty cool game. I was able to unlock all the content except for about 20 of the hallucinations, but I didn't really feel up to grinding for those.
I actually got stuck for a while on #2 of the crossword and just had to keep guessing random muscles until I got it. Felt like I was brute forcing the solution, though.
I also don't know morse code so I tried putting the file into some decoder website. It took a few tries and gave me a different output every time, but I could figure out the domain by going on what the previous domains were.
