I have a different opinion. I actually did a lot better without taking notes like this. When this jam began, I searched for tips on how to do successful in a game jam and one of the things was to take notes and plan your stuff. I did do that, especially for a state machine for my game.
But I happen to waste a lot of time and not being productive whatsoever. Then I just winged it and thought of stuff on the fly. That's the type of person I am. I was able to think of ideas spontaneously and let it come naturally while doing the stuff and I got a lot of work done that way, instead of planning and forcefully trying to think.
Just want to mention this so people alike can read.
