For the Invisible Guests level, players need to find twelve places in the room that are extremely scary. Some of them are relatively hidden, such as sliding the mirror left and right to see someone under the bed, and the footprints on the ground after turning on the light. Only those who peek outside the door will appear.
1. First, you need to click twice on the quilt on the bed, and a hand will appear.
2. Click on the feet under the curtain and the hand on the window sill respectively.
3. Then click the rec in the upper right corner of the screen and the puppy portrait on the wall.
4. Find the tablet on the table and the bear on the top of the bookcase and click on it.
5. Then slide the mirror left and right and click on the black shadow that appears in the mirror.
6. Click on the light above your head to find the footprints on the ground and the person at the door.
7. Finally, open the bottom shelf of the bookcase and click twice on the vent in the upper left corner.
