So I know that solo, it's generally not plausible to have a full Indie Game developed for Jams like this.

For those who work solo or with a small team, what kind of length do you generally shoot for in Jams like this? Do you have a demo or a full game? A small full game that runs about 15 to 30 minutes?

I aim for 5 minutes. :)

We're thinking about it and we'll try to have a game which can be done in 10 min' max'
