Add yourself! To start off, hide your sprite. Then, add yourself as challenging mode in the first scene by importing your character, then add yourself again, but the sprite must be inserted, not a costume. Then, when you recieve 'Rave.', show yourself and dance. Project holds up to 50 people.
This is the most complicated Add-Yourself i've made. Look at my scripts and costumes, then you will get the whole thing.
