I am assuming this is your first game ever made. It's good that you were committed to getting something submitted to the jam. It would of been nice though it you expanded upon the Brackey tutorial a little bit. Like a dice the roll on the side which changes the ground direction depending on its roll etc. And a bit of music would of been a nice touch too.
If your just learning Unity, don't be afraid to reach out to me if you ever have any questions or a bug you can't fix. The Indie dev community is a kind and open place for you to explore.
