Pretty cool game. The world was intriguing and I wanted to know more about it. The art is pretty amazing and the SFX is spot on. The only issue I found was that the puzzles, some of them were literally just guessing what needs to be done. For example (to avoid spoilers I'll be vague), needing three of the thing you get and then handing them over to a certain someone that then gives you an item that you supposed to guess will yield the result of what allows you to end the demo. It felt like completely random stuff that had nothing to do with each other. This reminds me of the old "inflated duck" puzzle from The Longest Journey -- you just have to try random stuff to find what you need. It also doesn't help that you don't know what you can and can't interact with.
Otherwise, the game was fun and I wanted to know more about the world, where am I? Where I was in the place I was in? Why people are so non-challant about what I did? Etc...
Very good job and good work!
