It's a Register Project. You know what to do if you've seen this like, a thousand times. If you haven't, I'll explain. The character shown upon bootup is Cakebear, the example character. You can change this by going inside the project, changing it from example to blank, and adding your own character! Things you can change in this: 1. Character, obviously. 2. Description 3. Mechanic 4. Jumpscare (Removing the jumpscare is completely optional.) Would now be the time to punch in?
