I love the aesthetics of the game. The interface also works very well. It was fun to travel through this universe. It was enjoyable to discover things. The dagger might need some sort of clue. I had to use the hints to find it. But then again, I might have missed something.
The story is well written and leaves just the right amount to the player's imagination. I didn't find any new keywords in most of the dialogue though. Don't know if I did something wrong or if just a few words were implemented.
Music would indeed have been nice, but it works well enough without it. So no big deal.
It was really fun. I hope you will revisit this idea in the future. I'd love to find a few more keywords and explore the world (or another) again. :)
