damn we thought there wasn't a map available haha, we have been looking for one but couldn't find it. But to be honest it was really fun to do like 15 playthroughs on nightmare mode figuring out where all the paths lead and try to map it on our own! If you want I could send you the png without our walking paths if you want to post it somewhere! The easter eggs were actually pretty handy to spot if you were on the right track when you decided to walk through the forest :D
There is a green link under the 'Development' and also the 'Help/Faq' tabs right under where you play the game
