What are your skills? I’m throwing together a team.

Well, for the Jam you can do the team model. But you could also just do it solo if you want… Really up to you.

If it’s your first LD I recommend to attend it as an individual competitor.

I would actually recommend the opposite. It can help a lot with time if you have a team with clearly delineated responsibilities, eg: a sound guy, an art guy, a coder, etc. Having multiple people do the same thing can lead to stepping on toes so I would avoid that for such a stressful compo.
