This looks very cool!

1. What game engine are you using?
2. Is there a playable demo?
3. I would have liked to see how a creature responds to being attacked, a bit of combat.

Will it be Linux compatible?

does it work on linux?

Cool looking and creepy! I'm sure many will play it! It has that kinda air.
Good luck and keep the good work going!
One thing I can add: controller support - make sure that works flawlessly (it is really hard one to pin down).
