Hello! My name is cuewotted, and i just wanna ask for some tips for this jam, cuz this is gonna be my second game jam ever, with this one having only half the time of the other one i participated (PSGJ)
Find a team that you can learn from potentially or create your own thing and wing it as much as possible, you will learn from the craziness of meeting deadlines. Find ways to be efficient, network, ask questions, and seek feedback. Best thing I can say for the actual jam is to organize your time, set goals and time buckets for everything. If you spill over that bucket move to the next, you will run out of time and you will have to cut corners.
