Rubicon levels are stored anonymously for seven days, and then purged to make space. If you want your level to be saved permanently so that future players will always be able to access it, it's easy - just enter the details below and it'll be stored for perpetuity in the Rubicon Warehouse (and whenever anyone loads it in, they'll see your name and the level's title).
The "follows or solves" field should be used to say which level a solution was solving, or which level a puzzle comes after (so if you're designing a series of five puzzles, the second would have the first as its "follows or solves" field, and so on).
