You are not alone, we failed as well :[ We were going to start with the beginning, but started just only 12 hours before finish, and also I accidentally published prototype in game jam section :-/
write up a post mortem. what went well and what went wrong. i failed by not knowing how to code the main mechanic i was gonna use :D learn from it and try again in other jams. failure is the greatest teacher
I failed, cause I started a few hours too late because I was at work and stopped development a few hours too early because I was at work. So basically I didn't have enough time. It's not like I did something revolutionary.
