With the help of an AI I wrote, this update makes the Imperishable Night reasonably possible to beat. In order to do so, the following changes were made:

• The Imperishable Night now starts with 120% power.

• Fixed a bug where Youmu could still jumpscare you if Satori was in your room.

• Koishi no longer takes a direct path to your room. She's also now slower overall.

• The music box no longer goes down if Youmu is in your room, but only if the camera is down.

• An extra phase was added to the power outage sequence.

• Power outages now stop Yukari even if she was in your room already.
