hello! i saw that some people have made logos before you start a game. i was wondering how to do that or if someone could do it for me.

Well, in order to make yourself a logo you need to first think of something you like and exaggerate it into an animation. Say you like 80's you could make the screen seem like an old TV then have it show your profile pic. At the end of the animation you have it broadcast the message to start your project.
Do you need further elaboration? If so ask!

does it take a lot of costumes, backdrops ect?
