Out now. You are a small light in deep water: eat the one cell you can digest, grow longer, and try not to meet yourself in the dark. A run takes a few minutes.
A gentle drift through a living column of water.
Guide a softly glowing creature as it sinks deeper, lighting the dark in quiet pulses. Easy to fall into, easy to leave. A few calm minutes whenever you need them.
One hand, one finger. Drag anywhere and the creature swims to you, settling just short of your fingertip so your hand never covers it.
THE WATER IS ALIVE
Light drifts past you. The current leans on you, then lets go. Everything down here is breathing at its own pace and none of it is in a hurry. Nothing flashes, nothing sounds an alarm. The dark just gets deeper and stranger the further you go.
FEED, AND GROW LONG
Every light you take makes you longer and a little brighter, and the note you hear climbs with you. The trail you're proudest of is the one you have to swim around. It's a slow and rather satisfying kind of trouble.
LITTLE IS LOST FOR GOOD
The water can take a piece of you, but it keeps it close, still glowing and still yours if you turn around and go after it. You can be careless down here and still be swimming a minute later.
SINK, OR DRIFT
Go as deep as the dark will let you, or take two quiet minutes and see how bright you can get. Either way you can put the phone down whenever you like, and nothing is waiting to nag you when you come back.
