> So in a way this is game programming without the concept of time.

A. You can't have a real time game without the concept of time. If you're making a turn based game, time is ignored equally in a traditional game engine.

B. Most game engines that have a built-in physics engine abstract away time to the exact same degree that React Game Kit does. Everything is about responding to collision events, applying forces, spawning animations, etc.

I am not saying it's not possible. I meant it's interesting to think about it as concept.

OK, but my point is that it's also a concept in most game engines.
