Remix and add yourself! also press space to switch between costumes. p.s. i had to put the rules here: 1. add any of your main characters to the project. Make sure the size of the sprite isn't too big. 2. then, add another sprite, make sure it's a blank one and the sprite is vector format. 3. Put some text in the vector sprite with your character's name, then put the number of how many costumes it has. 4. finally, put a script in your character like this: when space pressed with next costume under it. 5. you're done! just click remix, add some notes and click share. good luck!
note: i added the rules in the instructions so it's easier. i added myself in sonic advance style... which i still haven't finished. credit to all.
