Go Nerding (variant games)
I was thinking about limited information Go variants in the shower. There are a few around, but I've not yet come across the exact sort of thing I'm thinking of (with enemy stones blocking visibility).
I'm tempted to play around with the idea now.
If I could whack together a quick-n-dirty Go engine to tweak in something like Unity/Godot, I'd do that, but I cannot.
(The idea of doing it in Twine amuses me, and is quite feasible, however. Or a Discord bot, which is an idea I've played around with in the past.)
