Here, I show the changes I've made for 0.1.0, especially the custom playable characters.  So far, I've added the ability to set the custom characters' speed, max health, graphics, attack power, whether their bullets spread or not, whether they spawn hearts or not, and that's about it.  Someday, I know I want to add things like custom abilities, a magic system, flight, double-jumping, etc., but for now, this is what I have.
