Participants were given 4 hours to attempt 20 challenges, 2 of them came very close to clearing all twenty in the 4 hours. I made this CTF with no sleep in 24 hours, then lost all the challenge files and made them all over again 30 minutes before the CTF. But it was a very rewarding experience and I’m glad I did it. Thanks to garuda for making the reverse engineering challenges
