There's a post-ludum section now!
This Ludum Dare was a lot of fun, and I am really happy with the way my game turned out, despite all the fidgeting with the physics to try to make it feel as good as possible, and despite the fact I didn't get time to include audio in my submission.
I've spent the last week iterating on the game and creating a post-ludum section, featuring awesome physics!
