Wow, this one's a contender for my favorite of the whole jam. It's seriously great!...Was already my opinion. And then I decided to brute force the tablet puzzle, which was a ton of fun! I don't know if there was any additional info aside from that one letter, and I'm definitely still in the dark for some of the words, but I JUST managed to eke out enough of the words to discover what to do! I then did a quick second run with that knowledge, just to see the silliness that ensues.
I did run into a bug. You can run away from the multibeast and flee to the cave even if you haven't beaten the guardian yet (and maybe to the other locations? I didn't try those), which lets you skip getting the axe. Also, if you wait to grab the soap after you sleep, you can keep it throughout the whole game. I was slightly disappointed that it didn't have any effect on the boss that covers you in oily residue. In any case, I ended with the dog and owl medals. Can't even begin to imagine where you get the others.
