Once you’re in the app you will see different tabs. The first tab is called “Drafts”.
Drafts are blank or unfinished projects where you can create games. Once you publish your draft it becomes a published project visible to the whole community.
You can not only publish drafts but also duplicate them to test different variations of your game. This is also where you'll find remixed projects from other users that you haven’t published yet. Simply delete any drafts you don’t need anymore.
