Cardio Critters
A pet that runs on cardio. Excuses? None.

You run. It lives. You survive.

A punk tamagotchi that eats nothing but kilometers. It makes it through the day only if you went out for a run — simple as that. No training plans, no motivational coaches here: it’s just you, the asphalt and a critter that won’t buy a single excuse.

The deal

Forget about willpower.
Here, someone depends on you.

Your critter lives in a damp basement and feeds on your energy. The day you don’t go running, it’s left with no food and in a foul mood. Yes, it’s unfair. It’s also exactly what’ll get you out of bed tomorrow.

At first — Mild decline

It forgives you. Looks at you with sad eyes. There are still treats in the bowl.

If you slack off — Pressure

No spirit. Barks at you from across the room. Every notification reminds you.

If you abandon it — Critical

Serious condition. But recoverable. One good run changes everything. Your call.

The core loop

Running is the currency.

There’s a single currency: energy. You earn it by running real kilometers and spend it on everything else.

01

You go running

Every km counts. Real energy, earned with sweat.

02

You feed it

Stats blazing. Hunger, mood, health.

03

You send it on a mission

Leave it a few hours and it comes back with loot and good stories.

Energy

Energy

Every kilometer fills it up. You run, you earn it.

04

You activate buffs

More energy, better loot, exploration charms.

05

It levels up

Achievements, streaks, epic drops. More efficiency.

06

It stays alive

Emotional attachment. Tomorrow you run again.

Three stats. Zero spreadsheets.

Caring for it takes a minute.
Ignoring it shows right away.

Three bars, each with its own thing. Dropping them is free; raising them costs energy, and energy only comes from your legs.

Hunger

72 /100

Affects the energy you earn running. Let it drop and every kilometer pays less.

Decays fast

Mood

85 /100

Determines the quality of the loot your critter brings back from missions. Sad = mediocre drops.

Decays at a medium pace

Health

90 /100

If it falls too low, your critter can’t head out on missions. And nobody wants that.

The whole game

One app, one critter
and a guilt that won’t let go.

Missions

You send it on an adventure.
It comes back with stories.

Asynchronous missions: you pay energy, wait a few hours and your critter returns with loot — or at least with a good story. Risk and reward with a basement smell.

Streaks & Energy

Keep the streak and watch the habit stick.

Streak on fire

Achievements & Medals

You collect them, you show them off
and you earned them the hard way.

A pile of unique achievements and several repeatable ones. Some drop almost on their own; others will cost you months of legwork. Each one comes with its hand-painted medal.

Centurion — kilómetros acumulados

Your wall of fame.

Behind every medal there’s a run you’ll remember. Each category tracks its own progress, and leveling up drops loot too.
