I just gave it a quick spin, and will definitely play it a bit more before I rate!
Absolutely stunning visuals, this game has a really nice atmosphere.
The controls feel a bit strange (for keyboard). Maybe some of it is just getting used to it, but I still don't know what q and e turning is for when w doesn't move in the direction you're turned, but rather based on camera? Also - camera control could be more responsive. I suppose it's a choice to have fixed rotation angles as targets instead of continuous rotation, but perhaps allow canceling rotation by pressing the other direction?
Edit - after a bit more playtime:
There seem to be some frustrating invisible walls in some places - edges that F1LL should easily be able to scale to get to a location but can't, and then you have to go around instead - the purpose of the structures you affect with F is not always obvjous.
I did have a strange bug where Bo suddenly got transported to the ocean and changing to F1LL did not move the camera. Didn't manage to reproduce it.
All in all a very enjoyable game!
