What Yän said, the most important tips are also on the Jam page.
Are all of the rules and the general "game jam" procedure clear to you?
Don't hesitate to ask if you have any concrete questions. :)
Yup, completely clear :)
I was want to tell you thanks for all the videos you make, its helped me learn so much about game dev and what it is like to ve a game dev. I just started being a game developer, I posted v0.0.1 Battle Slime(my first game) a couple of days ago, its not much yet but this is just the prototype and it will get a lot better.
