This was my first Game Jam, and even if I worked with a friend who had some experience with them, I didn't know what workflow to expect, so when the Unstable Theme came out I was mentally already thinking about how to work a PC prototype first. However this was the result: an Android Game using the accelerometer as a main feature. https://ldjam.com/events/ludum-dare/49/extreme-restaurant-simulator

I was surprised how fast we came up to the initial concept. First, we looked at Unstable with the most logical stuff: something that causes explosions, maybe chemical, or just a lack of balance, even deconstructing the word as Un-Stable and then creating something involving animals. I was fidgeting with the phone in the hand, and the "lack of balance" Concept made me think about balancing something through the accelerometer, with controls similar to a driving game. So I said "What if there was a tray with stuff, and you are a waiter trying to balance it? Through the accelerometer." In my head it was a waiter going from the left to the right on-rail and you have the classic sidescrolling 2D experience. But my colleague Contro1990 surprised me by replying:"Yeah, the phone could be the tray and you have to hold it like a Tray!" And this subverted my expectations and cemented them: from a simple thought we went from something that could've been made for both PC ( arrows ) and Android, to something where the phone is the main instrument of the gameplay itself.

Then the development started after about 1 hour from the start, which saved a LOT of time.

I don't know if this is the usual train of thought, or even if there is a norm for concepting for a Jam, but what are your thoughts about that? I'd like to know more about your experiences, if you had some.
