Bonus Game Play?????

Just an FYI for those trying to decide to purchase this game. The developers integrated the bonus play (and I won't say how and spoil it) within the basic game play. If you go to bonus game play after completing the game, there is no bonus if you followed the SG during the game and collected certain keys, which the SG instructed you to use. Kind of a bummer

Note that the bonus play will not be present in the SE when it is released. Just an FYI.

In addition to the silver and bronze key places, everything past the gate in the manor backyard (which required the Gold key) is a bonus chapter.
