Replying...
Intro. On a typical day at a water park, you enjoy the slides and artificial waves. But after feeling strangely dizzy when you get out of the water, you discover that you have become invisible. No one can see you, although they can bump into you... you are tangible, but invisible. Now you must learn to navigate a world where people react with confusion, fear, or indifference to what they cannot see... and discover whether this condition is a gift, a curse, or an opportunity to explore the park's hidden secrets.

The water park has a secret.
