Thank you so much for the praise. We are really glad, that you enjoyed our game so much. <3
It sounds like you already did every available content so far and you have access to every room on the first floor inside the mansion. There might still be the debug menu for you to unlock, where you can view all the possible endings. For that you have to find 3 of the currently 4 available green crystals hidden inside the mansion and have low corruption. (you can clear corruption by buying an item in the garden shop)
