No one cares, but I care. If hypothetically someone asked me "Would you get a Jojo mahjong game for three bunks?" I would answer YES YES YES. So here we are.

It works just like their other mahjong games: 2-player mahjong with powers. (Un)[maybe]{depends}fortunately this isn't hentai so this is much more of a budget project. There's no hentai CGs or voice acting to speak of. Still, it's filled with neat refs and fairly entertaining on its own merits. I'm sure it's even better if you can actually read! Haha.
SPLUSH WAVE makes good stuff. If you can, please support them by purchasing their works. In this instance though, I don't think anyone else's gonna bother to put the game out.
