Thanks for the feedback! I'm pretty happy with the version (v0.5) that is currently uploaded and playable embedded in the itch page, so hopefully you get a chance to take a quick look at it just to understand the direction I was heading.
I chose Mancala, a board game, to make it intuitive for someone who has played before. It's my first SNES game, so I tried to minimize the dependence on specific hardware features in favor of simply completing a project. But Mancala has the same pitfall as implementing Chess: if you know the game, then there's no need for a tutorial, but if you've never played then it can be completely incomprehensible 😢
