I've gotten 3 endings so far, the ones I haven't gotten are C and E. I'll come back for them later, but any hints?
In the lower left corner of the map, there's a cave with another human. Listen to what they say for a hint for C.
Hint for E: Maybe there's someone else who loves wood ;)
Thanks! If you ever plan to update the game, maybe you could make an ending where you throw the seed in the river. Another idea I had was annoying the cloud power-up until they do something.
