I have several friends and strangers I’ve introduced witchball to and many of them love it. It reminds me of an old experimental 1v1 game called Pole Riders by Bennett Foddy, which got a sequel in Sportsfriends. I was wondering if you would consider making a sequel or a more feature rich update? And if not, do you mind people using this idea in their own games?

I wouldn't mind revisiting it someday, there were a bunch of things I couldn't do in the original for technical/sanity reasons lol. If I were to do that I'd definitely look for a lead programmer that wasn't me, at the very least, since I'm also pretty tangled up with another large personal project and it would really benefit from someone with better technical skills. As far as folks using the idea I guess just go for it, haha. I mean it's out there now, and if you'd like to expand on it then that's cool.
