You are the Entity. You don't know what you are. You don't know why you're here. All you know is one thing : GROW! Grow! is an incremental survivors-like with idle progression: every run makes you permanently stronger. Start at the atomic scale. Tear through particles, nucleons, and molecules. Absorb their matter. Level up. Get stronger. Then do it again, bigger. Molecules. Bacteria. Cells. A tardigrade. Tadpoles. Insects. Animals. Humans. Buildings. Satellites. Moons. Planets. Stars. Nothing is beyond your reach. Every run pushes you further up the cosmic ladder, from the subatomic to the astronomical. Grow! is a survivor-like action game where scale IS the progression. Fight through waves of enemies that grow as you grow, loot gear, unlock abilities, and build your Entity into an unstoppable force, across runs that span the entire known universe. CORE FEATURES ◈ SCALE BEYOND IMAGINATION Progress through 20 tiers of reality : from particle physics to astrophysics. Each tier brings new enemies, new challenges, and a mind-bending sense of scale. ◈ DEEP META-PROGRESSION Every run matters : Unlock permanent abilities, upgrade your Entity, and push further than ever before. The meta-progression is massive: there's always something new to chase. ◈ LOOT & EQUIP Enemies drop gear. Spend Matter, the universal currency, during or between runs. Craft your build, find synergies, dominate. ◈ COMPETE GLOBALLY Asynchronous multiplayer leaderboards : How far can you grow? Compare your highest tier reached against players worldwide. ◈ STRIKING MINIMALIST ART Black, white, grey, and yellow : Clean vector visuals with a bold, distinctive identity.
