Before I wanna say, that played the demo like 4-5 hours and this is just my opinion on everything I got.
I really liked the balance of collecting and searching. For a demo really well made. The music was amazing and fits the game really well. I also love that you have to explore the map in the way the creator made it. But there are still a few things I wanna say that need to be fixed:
No save after you change the water level, Paulrus and Enemy voice only on left ear hearable.
After all I really think that this game is going in the right direction!
I would give 5 out of 5 Stars for the demo!
