Wow, that third boss (after c'thal) is evil. Having it spawn minions is bad enough, but the fact it cages you in and has weapons on all of the sides is just... w h y? If the minions push you into the wall, you are screwed. And they can quite easily do that.
That better be the final boss (for now, at least). It deserves it.
Good game, by the way. Awakens the inner macochist inside me.
