I like the concept, and it sounds like you've got a solid plan to put it all together on time! I'm guessing that you'll do overhead third-person perspective? I'm interested to see it in action!
I have a very ambitious dream game planned for this year, so I'm both eager and a bit nervous to get started. It'll be a first-person turn-based dungeon crawler (probably with no actual dungeons in the initial release). Various locations on the map such as shops will "change" if your party members get stripped in combat and run away to hide there. Like most of my games, I plan to keep working on it for at least one more year after release, but I'd like to have a fully finished mini-version of the story ready for the jam release. There are a LOT of different systems that I'll need to put together to make it work, so I'm hoping to have a basic playable version of the game ready by the end of the second week and focus on the horny stuff for the remaining two.
I also like using the forum, it offers a really good way of archiving discussions. One week into the jam, I usually post a thread for work in progress screenshots and concept art. Those are all still up for older Strawberry Jams, for anyone who wants to see the creative process of how the participating games were made.
