Nice work, its always great to see someone getting into their first gamejam, and then ending it with an entry. Youve gotten 1 round of full experience!
Just finishing a gamejam is an achievement in itself. Over 350 people signed up but theres only 35 completed games, so youre in the top 10% just for submitting something!
I hope you got something out of the gamejam though, I certainly struggle with procrastination a lot during jams as well. Its something Im yet to get a proper handle on. But I do find whether success or failure you'll always get *something* out of it if youve got the right perspective. Keep doing that and youll find every gamejam improves in some way :)
