Found a bug. If you build up rage to full before the final battle by attacking the elder tree or breakable obstacles, after the ordeal, no matter how many sheep are left, you don't get an ending. You can just go around the map in the special form. It's funny how you loose the abbility to jump down in it.
I got 5/6 endings:
1. Adios
2. Forever alone
3. Eaten
4. Futile
6. True end
Any hints on how to get the last one?
