I went in to check the details for game submissions and I saw the game jam timer had another few days added to the time. However, the rest of the rules still state April 1st as the deadline. Is April 4th the new deadline or is it still April 1st for final submissions?

I just checked the CSGC Twitter and it looks like they did extend the deadline:

CSGC- Computer Simulation & Gaming Conference on Twitter: "We are Extending the Deadline to submit to our #CSGC2022 #competitions to Monday April 4th.
