Floating islands and bioluminescent flowers above data stream waterfalls.

World 01 of 04

The Digital Gardens

Floating islands, bioluminescent flowers and data-stream waterfalls. Wind physics matter here, and so does knowing when not to jump.

Be first

Four steps to a key

No registration, no NDA, no waiting for approval. Download it and start looking.

  1. Step 1. Get the game

    Download the free build for your platform and play it once. It is a real game, not a puzzle box.

  2. Step 2. Open it up

    Unpack it, decompile it, debug it. Everything you do to your own copy is allowed.

  3. Step 3. Find a key

    Three keys, one per locked level. Each one is reachable from the shipped artifact alone.

  4. Step 4. Submit it

    Be first and the locket opens with your alias on it.

    Three key submissions in total, tied to one email address, for the entire program.

The reward

First finders join the White Hats.

The White Hats are the guardians who hand out quests in the safe zones. Crack a locket first and one of them becomes you: your alias, a portrait built with you, and one line of dialogue in a future version of the game. Permanent credit in the Hall of Fame. There is no cash component, and we would rather say that plainly than bury it.
