ORBIT2D

Orbit2D saves in the browser you play in, which is fine until you clear it or pick up a phone. A Colony Key is a code the game makes for you — no email, no password, nothing to remember — that keeps your worlds on the server as well, so the same colony opens anywhere you sign in. It is entirely optional; nothing changes if you ignore it.

No password, no tracking, no newsletter. The server holds your worlds, your colony name and — if you give one — an address to post a replacement key to.

Every part of Orbit2D that exists today stays free, forever — all twenty worlds, thirty ranks, twelve talents, nine objectives and every ending. The Charter adds things beside the game; it never takes anything out of it, and nothing in it makes you dig faster, build cheaper or level quicker.

• Ten more worlds — Tidehold to The Long Room, own seeds and save slots
• Five suit colourways — rime, ash, basin, fault, signal
• Three drone finishes — survey white, copper, night unit
• Name your colony — it appears on landing and in your ending
• A charter mark — on the title screen, quietly
• It funds the next round — one person builds this

You pay, you get a code by email, you type it in once — and the game keeps working offline afterwards. No account is needed. If you do make a Colony Key above, the Charter attaches to the colony instead of to this browser, and follows you everywhere you sign in.
