In future, you might want to include a way to quit the game from inside the game itself. =)
Yeah, that's fine. Just have fun and make something cool. =)
You're on your own when it comes to building teams, but you're free to work with as many folks as you like! ^^

Go for it!
Use whatever assets you have at your disposal. The goal is just to make some fun games. =)
