Hey i have also failed about two game jams due to deadline and bug fixes this time I put myself out of my comfort zone and actually set a timer for a day before the jam ended and got my game completed by then, I've also realised that sometimes posting an unfinished game is better than posting nothing as the community doesn't really mind a bitt of bugs and unfinished game if you have a great concept or fun gameplay it is supposed to be a fun event to try and push yourself to do better so don't stress it too much and just enjoy the journey and ride hopefully u have a better time in the next game jam you do
And haha unrelated to topic you can try my game too if you want hehe
