Hm... after giving some thoughts, I have decided against allowing it. My reasoning is... although I'm sure this is not what you do, but taken to the logical extreme, if I am to allow this, I think this opens the door to a technically incomplete game at 99%, with 1% added during this jam.
So... unfortunately I don't think I can allow it.
My suggestions are:
1. Make a sequel
2. Make a new game with the same characters
Thank you for your question! Happy jamming!! ^^
