Have you thought about making a boss and some other enemies?

I've had other enemy types planned, but haven't given much thought to a boss encounter. Since you don't have a way to attack in this game though, I'd need to think about how to implement such an encounter. Maybe a carefully orchestrated chase sequence where the pred can't despawn, or a timed survival thing?
But I do think I ought to add something in the next update to make things a bit more climactic.
