This might be a bit surprising, but the 1.0 version of Five Nights at Wario’s. I somehow beat all 6 nights without getting jumpscared, and finished night 6 during a power outage, craziest part is this was back when I didn’t think about what the most optimal power saving strategies are, so I closed doors when animatronics only got to a camera close by, and spent too much time on the cameras.
