Match 3 minigame for renpy (WIP) (Patreon)

This weekend I've started a match 3 minigame, with a bit of math, I've got the basics working, now I'm at the stage to decide what kind of game mechanism to put in the game.

This it where you guys come in with suggestions, I'm leaning on some kind of dragging action, but I'm willing to explore other possibilities.

Download the game from the attachments and give it a try.
