Mofumaro, a digital creature living in a sunlit room

NULLGAME DIGITAL LIFE

A digital creature
Mofumaro

Mofumaro doesn't talk. When it's happy it bounces; when it's lonely it watches you from a little way off. A small creature inside your phone that tells you everything through expression and gesture alone.

A pet that never speaksPersonality and memory accumulateRuns on real-world time

CONCEPT

It doesn't do as you say —
which is how you know it's alive.

Pet it and it's always pleased; feed it and it always warms to you — we deliberately did not make that kind of solvable pet. Some days it wants your attention, some days it isn't in the mood. Some are morning creatures, some are night owls. Live with one for a few days and you'll catch yourself telling someone "that's just how mine is."

It speaks in expression and gesture

No dialogue, no speech bubbles — feeling comes through its eyes, the tilt of its body, how it approaches, and the pause before it reacts.

Personality grows permanently

Clinginess, curiosity, stubbornness, sensitivity and more shift little by little with how and where it's raised.

Daily life becomes a record

Meals, petting, play, sleep, and time left alone all accumulate, feeding into its behaviour and your relationship.

AURA EVOLUTION

Around day seven,
a light only yours will have.

A Mofumaro's aura isn't a colour you buy and pick. From how it seeks affection, how it plays, its curiosity, its stubbornness, how safe it feels, and the time you've spent together, the colour that stands for who it is is decided for the first time. Age alone won't evolve it: only as your bond and its trust grow do the colour and its depth slowly change.

The evolution ceiling is fixed per creature the moment you meet. Which colour family it grows toward, and when the conditions are met, still change with how you live together. Even along the same 24 routes, evolution stage, mood, and the way it glows while sleeping all layer up — so raising two that look alike is not easy.

LIFE TOGETHER

Keep one ten years and you get ten years' worth of creature.

Personality, memories, and the bond all accumulate on your NULLGAME account. You can live quietly with one, or watch the small relationship between two. What we're building toward is a place where, ten years from now, this creature holds ten years of living with you.

A relationship between two

Sleeping side by side, chasing, jealousy, fights, making up. From how their temperaments fit, things happen that only happen with two.

Separate lives

Name, personality, mood, hunger, and sleepiness are tracked per creature. You can put one to bed and play with the other.

Toys and small discoveries

The items you own open up new ways to play, and whatever you find in the garden or on a walk is kept in your discovery log.

FUTURE DIGITAL LIVES

If you move from the free trial to a plan, you keep the same creature, and for as long as the plan continues, your time together keeps adding up.
