Played twice. The on-screen instructions help and I THINK I got the gameplay down.
The first time I was killed while scanning. I don't think I was waiting too long between scans but the bear showed up quicker than I could put the scanner away, turn, and grab the gate.
The second playthrough I guess I died because I let go of the gate too quickly. I saw the gate bent initially but nothing after that, no visual cues on if it was safe or not.
You credit sounds but I didn't hear any while playing?
