I wish there was a walkthrough for achieving endings... So many variants...
Oh my gosh! I totally forgot, haha. I'm doing a lot of game jams this year and it's been a marathon.
**SPOILERS**
Eat the normal charcoal, knock on the tree with the body hanging in it (there's one tree that has a body all the rest are the same two trees) and the person with the unreadable scribbles is the person to kill, there's a hint to that in the newspaper at the beginning. Hope this helps!! It's a dark game for sure, don't feel any pressure to go through it all again. Thanks for giving it a go!
