What you get

Chapter 2 carries the whole arc of the game to a second world: a frozen, rust-red desert dragged, storm by storm, toward something that could hold life. It's a full new planet across ten visible stages — the red rock you start on grows before your eyes as your Stardust climbs, all the way to a living world. The last stages stay hidden until you reach them yourself, in your own save.

How it works

Checkout opens in a secure overlay right on this page — no redirect, no account to create. The moment your payment goes through, PlanetIdle issues you a license key and applies it automatically in this browser, so Mars unlocks immediately.

Save your key. It's your proof of purchase and it unlocks Mars on any device — just paste it into the game's Worlds screen on your phone, laptop or tablet. Lost it? Restore it below using your transaction id or the email you checked out with.

Frequently asked questions

Can I get a refund?

Yes — every purchase is covered by a 14-day, no-questions-asked refund policy. If Mars isn't for you, just ask within 14 days for a full refund.

I lost my license key — what now?

Use the Restore box above: enter your Paddle transaction id (from your receipt email) or the email you checked out with, and we'll re-issue the same key. Still stuck? Email [email protected].

Does it work on my other devices?

Yes. Your license key unlocks Mars anywhere — paste it into the Worlds screen in the game on any phone, tablet or computer. There are no accounts and no device limit.

Is Chapter 1 (Earth) still free?

Yes, forever. The entire Earth story — from a barren rock to the star-gate — is free with no ads and no sign-up. Mars is the only paid chapter.
