The theme was "You are the Villain." I decided to make a game about being an old timey villain who ties women to train tracks.
The first 24 hours were pretty slow and I didn't have a lot of confidence in my idea, but I eventually picked up some momentum at the end of the first day and finished strong. I'm really happy with how it turned out.
The game is called "(Tie One Woman to a Train Track and Suddenly) I'm the Badguy". Get it on the ludum dare page.
