On the way back, this path will open up inside the cabin. You'll need to grab a rope; after grabbing it, just return to the hole.
Let me give you one more compliment, you are a very talented person, it will be great if you do not give up your game and continue to improve this game, I really like it and I want to play the sequel to your game. I really like the RPG theme. You can make the cutscenes longer because they're pretty short now. Thank you for your game, I will be keeping an eye on the sequel and your other games. You can do it!
