What you can do
- Seeded worlds. Every world grows from one number: hills, lakes, sandbars and groves, identical for everyone who uses the seed.
- Dig and build. Break any block with a click, place ten materials with your other hand, stack cairns on the ridgelines.
- A moving sun. Ten-minute days sweep from copper dawn to indigo night, with stars on the dark side.
- Physics you can trust. Gravity, jumping, collision, swimming — you never sink through the world.
- Mouse, keyboard, touch. Pointer-lock look, arrow-key look, on-screen joystick and buttons on phones.
- It keeps your world. Autosaves to your browser; start fresh with one key.
