Not working on a pinball game, but I've been a Big fan of the good old Pinball Fantaisies!

Ah ah ok, I didn't know this idiom 😅

I've read a lot of stuff on that matter, the most famous being the case of Mino (en.wikipedia.org/wiki/Tetris_...). But I don't find anything about grapevine. Could you be more specific?

But it's not completely lost, I started working on a new game with a unique gameplay this time. I kept the same visual design though. I'll post more soon...

Why I won't release it? Because I realized too late that making a #Tetris clone is too risky on the legal side.
That's the problem when you keep working on a proof of concept 😅

Rider is always opened, sometimes Blender, XnView, Fork of course and recently Audacity

I fear that you won't get much attention with just an idea. I think the minimum would be a Game Design Document. But it would be better with a demo.
