Make a path.
Make it your own.

Rescue the foundry crew, then change a mission and keep a credited copy you can reopen.

Alpha: browser gameplay, native downloads, mobile layout and human game feel are not yet verified for this hosted adaptation. Known input-cadence differences remain. You can also download the complete workshop to inspect and open locally.

  1. 1. Play the first shift

    Choose Start mission. Use arrows or WASD, Space for a charge, Escape to pause.

  2. 2. Change one thing

    Open Remix this mission. Choose Floor and remove one crate, change the title, then Review & play draft.

  3. 3. Keep the remix

    Choose Prepare credited JSON in the editor. Then use Download level-pack JSON in the file panel below.

  4. 4. Reopen your copy

    Open a fresh workshop tab, select Level pack and your downloaded JSON, then Review import in game. Start explicitly.

The foundry

Preparing the isolated game. JavaScript is required to play.

No automatic saves. Keep a downloaded checkpoint or level pack if you want to return.

Keep it, then prove you can reopen it

The game frame cannot download files or show browser confirmation dialogs. These separate controls handle your chosen JSON files. Nothing is uploaded or automatically imported.

Download prepared work

First choose Prepare credited JSON or Prepare campaign checkpoint inside the game.

No export prepared yet.

If downloading is unavailable, copy this text into a UTF-8 .json file. Reopen that file to verify it; selecting or clicking is not proof of a saved file.

Reopen a file or pasted JSON

Selecting a file only prepares a review. The game stays unchanged until you choose Review import in game.

Two different files: a level pack stores editable missions. A checkpoint stores that pack and completed mission results. Neither saves a live attempt, positions, health, enemies or fuses. Checkpoints resume at a mission boundary and exclude editor drafts. Preparing a level-pack export captures your current draft mission; keep it separately from the checkpoint.

This hosted adaptation adds an opaque game frame, explicit local-file transfer and visible replacement decisions. The engine, campaign, checkpoint rules and simulation clock are preserved from the original offline foundation.

The HTML is self-contained. The ZIP includes readable modules, styles, credits, tests and rebuild instructions. Keep a clean copy, change one thing and verify your own remix. Exporting a pack does not publish it.

Automated non-browser checks exercise runtime behavior and transfer boundaries. They are not rendered playtests or proof of native file saving. The original six-mission simulation evidence is separate from this adaptation’s evidence. No full-game human completion, accessibility certification or browser acceptance is claimed.
