I'm in Act 3, in the process of collecting the >!three hearts.!< I've tried looking this up multiple times but still have no answer. It looks like there are rooms to the left and right of this area below Bellhart that you access through the bell station. Do they actually go anywhere? The maps I have seen don't show anything. The unmarked places typically connect to rooms I haven't accessed. This has bothered me for a long time so I am asking about it instead of wasting more time beating the walls to death. Are they only accessible through a particular run or something? Thanks
