I had a dream about "a megalovania" (a bad-time/no mercy boss? It was definitely set to Megalovania) which Toby Fox had apparently made in some older version or other of RPG Maker. The boss was this cute-but-determined anime girl, I think. You could still productively use ACTs, and there was one ACT where, if you used it repeatedly, she would flip out at you and her next attack would be harder to dodge.
