From the rules:
Ideally, games should be new, but if you really want to dust off something you once started, that’s okay — just let us know where you were starting from. (There’s a field when you submit a game.) Just, you know, use your judgment. Don’t take something that was 95% done and polish it up for this jam.
So I guess just let everyone know what you’re starting from and whats new and you should be okay? Sounds like you’ve at least still got animation work to do on your assets that you can do in Febuary as well as actual development.
