Ah, I see. Yes, it explicitly mentioned that the demo ended after I found out about the item that was required for the fountain. It was quite interesting, but I don't recall the map showing it (or maybe I'm just misremembering) so maybe that's why.
I enjoyed the game, I hope that the settings could be kind of more intuitive early on in the game. I had no idea I could switch from WASD to other forms of navigation until I was decently into the game. I enjoyed the small 4 person rocket game though, it was a fun way to play through and get more dice that way. There is only one treasure map so far, right?
Also, I liked the sound changes in various places, such as the Ferris wheel (which really stuck out to me for some reason) and the night time area (and the lack of sound in the tunnel). I liked going through the game, looking forward for the updates!
