Heard that usually for game jam, people create 2D games because it generally faster to make.
This would sound like a really good advise for me as it is my first game ever game jam and first ever game made and "published" online, but somehow I decided to go "hard mode" and yolo with 3D games.
Certainly a lot more hardship than anticipated, especially in the graphic/presentation, but I guess the experience is worth it.

Its kind of a survival(?) game where you need to help an innocent girl transverse through a dangerous warfield, armed only with... your leg and your wits! So get running.
