"REMEMBER, try to build your game as early as possible so that you won't panick in the last minutes of the jam because some stupid problems occured similar to how I did."
I agree with this 100%! We had problems when finishing up last night when we did some testing and discovered that the UI wasn't scaling correctly when the game was played in fullscreen. My teammate ended up having to completely remake the menus, so we lost some time there but thankfully we were ahead of our schedule so it hasn't destroyed our game jam attempt yet!
