Darts minigame for renpy (WIP) (Patreon)

This weekend I've decided to re-create one of my oldest minigames. Oddly, this time the main difficulty isn't the code. It's drawing the board in photoshop, and the masks that I need to figure out where the dart has landed.
The board came out fine, but the anti-aliasing that can't be disabled in photoshop is making my life a whole lot harder. I have to go back and paint those pixels between colors one by one. But that can wait till next week when I add the scoring system. For now, enjoy throwing some darts pointlessly. (you have to pull out the darts, I only had 3 of them)
The code is in the attachments.
