Gomoku minigame for renpy (Patreon)

I've been looking for an opportunity to fire up my old PC and search through my archive for this old minigame I've coded a year ago. Never had the time and parts to do that till this weekend. Finally done it an now you can enjoy (or suffer) this antique with all of it's flaws.
I've mended the code and made sure it runs on renpy 8.x, just don't expect too much from it, the AI is kind of dumb and can't ever win against players.
The code is in the attachments.
