Hi there and thanks for reaching out! Great to read that you are working on something, and amitious sounds good, looking forward to that! :-)
About your question: The rules state that the game has to be finished by the time the Jam will be over. However, that does not mean that you have to release the full game on that very same day, but at least the judges would need to have that version by then. For that, just reach out for contact info when the time has come (you may of course also do so before), send it over and I'll sent it to the other two. Hope that helps.
