I'm glad you learned so much from the Game Jam! :D
For me, the things I learned were:
- Proper time management.
- How to effectively fight scope-creep.
- How to work in a high-speed environment where results was the most important aspect.
- How to build and export WebGL games.
And as a bonus; I learned I really hate writing sloppy code.
For me, the Game Jam was a big mix of a LOT of hard work and just a little bit of fun. To be honest, the Jam only became fun right around the 45 hour mark where my project really started to come together. :c
But all in all, I am thrilled I was able to completely my game within the 48 hours and I consider the project to be a complete success (considering its my first Game Jam). :D
