Thank you very much!
Ending I and VI are a bit difficult to find, due to them having only a single specific way. As a tip: Ending VI requires making the Ghoul too powerful and Ending I the 'correct' way to make a +1 Ghoul and avoid all other mistakes.
My associate and I definitely plan on updating the game once the jam is over, because we couldn't implement all planed features due to the time limit.
