The new due date for all jam submissions is April 18 at midnight. The original due date was incorrect, only allowing 24 hours. 

Keep in mind you can start work on the jam now, you just need to say when you began the project in the description of the game for judging purposes.

Personally, I am very anti-crunch culture. Otter Jam is meant to be a community event for learning and working together. It should not be a cause for lost sleep! Take care of yourself, even when working hard on games.
