Prototyping a Game Engine or Something Like That?

I was wondering, like, in the direction of continuing to do that. What does your prototype process look like? How do you build this stuff? And imagine the stuff it feels like? Are you doing prototyping just with like, math equations at a super low level? are you doing stuff on paper? Like, how doyou how do you even find a puzzle like tantas ot? For me, i think it's more about, like, maybe i read a book or like a, like,Maybe i find like, watevid or something that, like, thereis something about geometry or something. And then i feel like, oh, this is, this is interesting.
