Not only new to jams, but new to game development in general over here! I cycled through several ideas but I don't actually have the experience or abilities to do any of them. What I AM going to, though, is make a basic kind of game in the gameboy style and get it as polished and complete as I can before the deadline.
I'ts hard to avoid scope creep when you know almost nothing to start with. ANYTHING I plan is going to be more than I can do right now. I have to work hard to keep the project even remotely plausible.
