Looks good. I would like a way to delete from only a subset of components also though. After a deathmatch is done I want to delete all data for that match but keep the ui in place etc.

I guess you could do that e.g. like this:

let delete: Vec<_> = (&*entities, !&ui).join().map(|(e, _)| e).collect();
world.delete_entities(&delete);

Or filter for specific components. I think the above code shows how flexible this is ;)

Hmm, cool. I missed that part :)
