Dude you rocked it with the openings and the story telling! great job! Also i know the headaches in dealing with HTML5 exports. I learned my first time just a bit ago! its amazing how much a project can change when you dont set it up for HTML5.
One of the things i did this time around was always test for HTML5 first. Because if it works on HTML5, More likely will also work on desktop like normal. or where ever else you are deploying to.
Keep learning and practicing your skills and entering these jams! you will get better. Cant wait to see your next project!
