This is my first ever game jam! I'm really new to game development and I'm still a student, so I don't have much time to work.

Does anybody have any tips for time management in a game jam?

I think the only solution is to make it simple
Its a game jam to test skills so making a simple and fun game will be the way to go
Managing time can be a pain so just make a simple game which you know you  can make fun just with some extra details

my best advice is dont give up!
