Both will come sometime in the future. My current focus is gameplay, but after probably 10 total levels I will start on things such as those.
I did have some ideas for customizing the player past colors, such as different bumpers/shapes which do different things, e.g., circle rolls, triangle breaks, but I won't know if they work until I test them. That said, these are future ideas. Though, I am open to ideas and suggestions for the future.
