Hello Keen. This would be a great foundation for a team. In the past I have made a virtual board game, a platformer demo, and a handful of experimental prototypes. I am not sure what I would like to make in the future, that is partly the reason why I joined this game jam. As for music, it will really depend on the type of game we decide on making.
Also, I tried to make a chat room in discord, but I am kind of new to it as well, so I was not able to figure it out. My user name is Gravity_Mx#1780 if you know how to do it.
