Crash, but there's no need for hosting! This works just like Changiosity, if you know what that is. (Don't go to its remixtree unless you want your device to crash 2.5.) In simple terms, you can change anything about a character, make them do an action, or add a new one. You can do whatever you want as long as it isn't too much. The rules are to follow scratch guidelines, and if someone makes a change you don't like, just don't remix the said project and, if it's regarding your own character, speak up about it. Also, I would put Pilotredsun's song "Greetings" playing in the background, but he said in a post that "You may not use my music for a game", so I just recommend you listen to it in the background while editing stuff I suppose. As replacement, I used the short song I composed for Nico's Custom Night.
