Action-platformer where you evolve a creature from prehistoric fish to land animal across Earth's geological ages. You earn evolution points by defeating enemies, then spend them to modify body parts—swap jaws for better bite damage, grow horns for defense, adjust fins or legs for movement. Progression isn't strictly linear; different stage routes and body configurations affect which encounters you can handle. You'll transition from ocean to amphibious zones to full land environments as your creature changes form. The story frames this as a competition among lifeforms to reach Eden and partner with Gaia, but a rival organism consuming mysterious crystals disrupts natural evolution, forcing confrontations in each era. Physical transformations follow rough evolutionary logic, making the biology semi-educational. Suits players who want deliberate customization over preset upgrades.
