Just checking did you ever crouch in the turret room?
No I haven't.
I thought I was supposed to "run" between cover. I was always 1 hop away from the cover so I thought that was what I was supposed to do.
With how close the next wall of cover was and the mini walls in between having noticeable holes, it lead me to believe that running by was the solution to the room.
I'll try the demo again with this knowledge and I'll edit my alpha 3.0 feedback comment based on the rest od the demo. But I still think that in the ice turret section it should be made clear, from the mechanical point of view, how to beat it.
Some kind of indicator or a sign on the wall indicating that the way of dealing with turrets is crouching would go a long way in this and future puzzles.
