selection screen for renpy

A character selection I'm working on. It has a robust random selection, unlock-able characters and can be expanded for more functionality.
At the moment it works perfectly with clicks if your game is single player, but I'm working to get it work with keyboard and hopefully when I bought a set of controllers, with gamepads.
It serves as a good example for any kind of selection screen if you need some code to start with.

Before adding it to my GitHub, it will be available exclusive to my patreons for a while: https://www.patreon.com/posts/selection-screen-32249316
