I did an RJ run today, and I have to say I like the new battle mechanics.

However, when the battle ended and the big pink guy exploded, a few minis were mysteriously left over. I'm guessing they might have been spawned by the polyps just as RJ was detonating.

Not a huge bug, but I figured I'd throw it out there.
