It is unclear how to win but I think overall it is a well made interactive fiction. There is a lot a dialogue. Mqybe you could try to ad some graphics showing the emotions of the characters? Just reading tends to get a bit boring.

You are quite right, it is hard to "win." It's pretty clear with comments, that story progress is too obscure. I will try to add more obvious direction for the player.
I did create a way to make some motion, and we did plan on having the main characters show emotions. Unfortunately, we ran out of time and decided the story was more important.
Thank you playing. We will be working on improving the game in an update.
