Publishing a level

1. In the editor, make sure the pill in the top bar is green (no errors), and that author and license are set in the level's settings.
2. File › Export level + pictures gives a .zip with the level and every picture it uses.
3. Submit it (sign in with GitHub first). The site checks it at once with the game's validator and tells you what to fix if anything is wrong.
4. A moderator reviews it, usually within a few days. You can follow it on your levels; if it is rejected, the reason is shown on its page.

Updating a level

On your level's page choose Upload a new version. The new version goes through review like the first one: the level leaves the gallery meanwhile, and comes back with its likes and plays once it is accepted.

Licences

Pick a licence that says what others may do with your level. Common choices:

• CC0: anyone may do anything with it.
• CC-BY-4.0: anyone may play, change and share it, crediting you.
• CC-BY-NC-4.0: the same, but not commercially.
• All rights reserved: people may play it, nothing more.

Whatever the licence, submitting a level allows this site to host, show and distribute it with its files (see the terms).
