Crystal Ecosystem

Crystal Ecosystem is an offline collectible creature game. You play a Crystal
Keeper: you hatch ancient eggs, raise the creatures that emerge, splice their
DNA, equip their skills and lead a three-creature team through five hostile
worlds. There is no waiting, no energy meter and no account — every egg hatches
the moment you tap it, and everything you collect stays on your device.

The loop is simple to learn and deep to optimise. Eggs come in four rarities and
each one rolls against its own odds table, so a Legendary egg is a real prize
rather than a slower Common. Every creature you hatch becomes a card with its
own HP, Attack, Defense, Speed, Crit and Luck. Upgrade a card to raise every
core stat up to level 20, splice one of five DNA mutations into it for a
percentage boost, and equip one of seven reusable skills — Dodge, Heal, Poison,
Double Hit, Lucky, First Strike or Thorns. Skills and mutations are inventory
items, not permanent choices: pull one off a card and it returns to your vault,
ready for a better host.

Battles are turn-based auto-battles you can read. Pick 1v1, 2v2 or 3v3, choose
which creatures take the field, and watch the fight resolve blow by blow with a
running combat log — dodges, crits, poison ticks, thorns reflecting damage and
heals when a creature drops low. Turn order follows Speed, with First Strike
jumping the queue. You can let it play out or skip straight to the result.

HOW IT WORKS
1. Open the Laboratory and hatch the eggs waiting in your incubators.
2. Upgrade your strongest creatures, splice DNA into them and equip a skill.
3. Build an active team of up to three and pick a world in the Battle tab.
4. Clear levels to unlock the next one, and beat the boss every fifth level for
crystals and premium eggs.
5. Spend your winnings in the Crystal Forge on packs and rarer eggs, then repeat.

WHY CRYSTAL ECOSYSTEM
It respects your time and your data. Nothing is gated behind a countdown, a
login or a purchase — the whole game is in the download. Progress is written to
your own device, so it works on a plane, on the underground, and anywhere with
no signal at all. The interface is built for one hand and for dark rooms: a deep
obsidian palette with crystal cyan, violet and gold accents, and no ads pushing
in between rounds.

PRIVACY / DATA
Works fully offline. The app requests no permissions, makes no network calls and
collects nothing. Your creatures, currencies and battle progress are stored only
on your device, and uninstalling removes them.

Start with a single egg and finish with a codex of 120. Your ecosystem is
waiting, Keeper.
