Doodle Cosmos

🪐 About Doodle Cosmos

Doodle Cosmos follows the same idle-clicker bones as Doodle Buddies, but themed as a solar system instead of a crowd. You start clicking a single hand-drawn planet -- Earth -- for energy, and that energy buys buildings that keep generating more of it automatically.

What gives Doodle Cosmos more long-term shape than a flat clicker is its unlock ladder: hitting energy milestones (300, 5,000, 100,000) unlocks new worlds -- Moon, Mars, and the Asteroid Belt -- each with its own color palette and place in your growing system. Six building types span from a cheap Bigger Scoop (+1 energy per click) up to a Quantum Drill generating 300 energy per second, plus a Warp Drive that multiplies everything by 1.5x.

How to Play

1. Click your planet to harvest energy -- this is your starting income before any buildings are online.
2. Spend energy on buildings: Bigger Scoop and Solar Panel are cheap early options, while Lunar Reactor, Fusion Plant, and Quantum Drill unlock later and produce far more energy per second each.
3. Reach energy milestones of 300, 5,000, and 100,000 to unlock the Moon, Mars, and the Asteroid Belt in turn -- each new world adds its own visual identity to your growing system.
4. Buy the Warp Drive when you can afford it -- it multiplies your total energy production by 1.5x rather than adding a flat amount.
5. There's no fail state or timer -- keep reinvesting energy into buildings to push your system's total output higher.

Early on, split spending between Bigger Scoop (raises your manual clicks) and Solar Panel (raises passive income) rather than dumping everything into one -- you'll hit the 300-energy Moon unlock faster with a mixed approach. Once Warp Drive is affordable, buy it before the next big building tier, since its 1.5x multiplier compounds with every building you add afterward.

Frequently Asked Questions

What do the unlockable worlds (Moon, Mars, Asteroid Belt) actually do?

Each world unlocks automatically once your total energy crosses a milestone -- 300 for the Moon, 5,000 for Mars, and 100,000 for the Asteroid Belt. They mark your progress and add new visuals to your system as you grow.

What's the strongest building to buy?

The Quantum Drill produces the most raw energy per second (300) once unlocked, but the Warp Drive is arguably more valuable long-term since it multiplies your entire production by 1.5x rather than adding a fixed amount.

Is there an end goal, or does it go on forever?

There's no fixed ending -- Doodle Cosmos is an open-ended idle game you check in on, reinvesting energy into bigger buildings and higher-tier worlds for as long as you want to keep growing.
