While I enjoy the new content, I feel like it is better enjoyed in smaller bursts-- I would like to take a break from a ng+ run to do a boss rush or a bit of roguelite-ing, but making it only accessible from a completed run with no further progression seems to wall it off unnecessarily. The new content doesn't seem to be deep enough to make me want to find all the drops in one go before starting a new game. (I do understand the spoiler implications of making it freely accessible, but making it open on an ng+ file would be awfully nice.)
