I'm using a 2D grid as my spatial hash. Bodies can be grouped in three different ways, using string identifiers:
Groups - the groups the body belongs to
Groups to check - the groups the body will CHECK collision with (and invoke callbacks)
Groups to resolve - the groups the body will RESOLVE collision with (they won't overlap)
The library handles 10000 bodies quite well as you can see in the video, but it still lacks features. Considering 500-1000 bodies are more than enough for any simple 2D game, it's safe to say performance won't be an issue.
