Hazel

If you're interested on a dive into building game engines, I've enjoyed some of Cherno's videos [1] on developing his game engine Hazel [2][3]. It's cool to see the amount of work that has to go into building an engine. I believe Noel when he says building games without a commercial engine is more fun - there's a lot of fascinating optimizations and tricks at the engine layer.

IIRC, all those engines provide an ECS that could be compared to entt. Also, there is Hazel[0] which is based on entt and is the subject of an amazing youtube series[1]. IMHO, tinier means less features, at that point what could be considered comparable?
