This is a rant I can support from all of my heart

AABB was perfectly usable for most games. I always thought that the latest A7 still had AABB because of the naming of "USE_AABB", but recently found it it uses ellipsoids instead.

So I took the only reasonable step for my game "Survive!":

I programmed my own AABB collision detection in lite-c. Its highly unoptimized but it works for the super small levels I have, and it includes the EVENT_ENTITY.
Its missing any kind of level-block collision though, so its worthless for you.
