Solo dev here, I think I got about 4 hours of sleep during the 48 hour jam time:
My game is a Metroidvania where you only have 1 minute to complete it: https://itch.io/jam/gmtk-2019/rate/462374
Played and rated! That one was a toughy! Couldn't escape, but I had fun exploring and finding the new items! The time limit made it real intense!
