The rules and description are clear here. You even pasted the section of the rules specifying the reliance of the game on MetaFab. Appreciate your submission, but because you didn't integrate MetaFab your game is disqualified. We host jams monthly. If you would like to participate in the future we will happily review MetaFab and integration requirements.

Keep up the good work :). Not knocking against your age or ability as a developer. Your submission is disqualified because the rules were not followed. Impressive work, and if you keep it up, you no doubt have a great future ahead. We look forward to seeing what you submit in the next jam. Feel free to jump into our Discord and ask questions about the rules to ensure your next submission won't be disqualified.
