So this one's probably just my potato being a potato, but the part in the Haunted House where the boss chases you around IS SO LAGGY. Ugh, and the game crashed when I went through the stairs after I lit the furnace.
This one's probably coded in though, when I reloaded and lit the furnace again, the room with the save point blew up when I went in and dropped me in a black screen. With the game-over-on-touch boss in it, naturally.
It's getting so the most terrifying thing about this game is anticipating the next crash and thinking about how it's mechanically going to screw you over next.
