Staring at the mirror (as most VRChat denizens do) removes your health. Linger too long, and your reflection fades from the mirror....until you step away, play some games, and enjoy the other aspects of VRChat. :)

We revisited the world today with a mostly-fresh group so they could explore the world with someone who knew some of the secrets. The new people did manage to trigger the 'bop' effect in the mirror but didn't understand the significance, and some couldn't trigger it at all until they rejoined. I'm sorry, but we won't be adding the world to the Featured row. However, we hope you find an audience that appreciates what you have made through the Community Labs sytem.
