(Spoiler alert)
Very interesting experience. I love stories that make me twink twice about the actions we take. The lore is interesting, the art is pretty good and I think you might have used a metaphor around friendship and the lighthouse, wich is something that I also liked.
I just missed having a little bit of freedom choosing who to trust, but I know this would make things too complex for a free game.
Anyway, good job guys!
