I'd encourage you to submit something and not overcomplicate things (second jam here, so not an expert by far...).
If you have two days, make a simple project that don't need hours and hours of code. Yes, I know it's so easy to say and not so easy to do and yes, maybe it will not be your best game but you'll submit anything and gain experience on that too.
And who knows, maybe something super-simple ends up being more fun and enjoyable than a super-complicated project. You can keep working on it after the deadline if you see that it have potential!
Cmon! You can do it!
