If your team cannot even agree on something as simple as a name, I would submit that your team has bigger issues.
That said, being a solo dev is far from easy. You have to be a jack-of-all-trades to make a game look presentable, playable and fun. You have to know how to code; to make your game function in the way you want it to. You must have some background in the arts and music, even if it is self-taught and lots of practice.
Try out some smaller jams to give yourself a chance to practice, even if the game does not score well; it will build up your capabilities and help you tackle larger projects down the road. It never hurts to start small.
