@eb948c00 Currently developing with Flecs, I tried Entt a bit a 6 month back so I don't know any recent development, however, Flecs is mature and by far my favorite framework but there is a bit of a steep curve for creating a good workflow, it really force you into a functional paradigm and the filters (rule, query) are very powerful, they can be a bit hard to map mentally
Anyway, highly recommend! 

 @e948c5fa nice, thanks for the input
