Are there any events that can be missed in The Longing?

Solution 1:

There are two events that can actually be missed but you do not need to be afraid of it because ...

there is a way to go back in time.

They are :

Shade birthday (365 days after the start). A special event happens in one of the cave which is key to one of the endings.

Old man death. On the overworld there is an old man that periodically use the well. One of the endings is linked to him.
