Walkthrough
Enter the castle. Inside, to the west of the entrance, there is a face stone. Push it, enter the hole to the right, an elevator will bring you to a small platform, find the blue key here.

Go up the wide staircase, enter the blue door, go through the only other non-keyed door. Go up the stairs that will split but lead to the same gallery. Enter the door at the other end, try to push the figures, one of them will open. Go through and to the room before the balkony. Activate the face stone. Go back and through the second, now open, figure. At the end of the hallway, there is another face stone to push, opening the remaining third figure. Behind it, follow the stairs to the top gallery. Jump down into the area with the river. Jump down into the room the river is running into. Climb the ladder into a small room with torches. One of the walls can be opened, revealing a teleporter that will bring you back to the bottom gallery. Go down one of the stairs to the point where they re-unite. You can now go up between them and pick up the red key.

Enter the red door (to the left of the blue door), you will reach another door, behind which stairs lead up to a room with fireplace and bookshelves. Go down the stairs at the left side (not all the way to the river) and activate the red skull stone. Go back up, one of the bookshelves has opened, so you can reach a balkony with three green face stones. Push these stones, one of them will reveal a teleporter. Use it, at the destination is another teleporter to bring you back later. But first, go down the stairs, go through the door and onto the eastern balkony where the yellow key is awaiting you.

The red and blue door's hallway has yellow doors at both ends. Go through any of them, you will reach the big open area in the north-west. There are four tiny balkonies accessible from galleries behind. In the small room leading to the south-west balkony, there is an "X" on a wall. When you push it, the backside of the nearby column (at the top of the stairs) will open, push the face stone inside. The equivalent column at the opposite (eastern) side of the open area will open, releasing an Arch-vile. Inside is a teleporter to get you to the tower in the middle of the open area. Enter the room in the tower's center, push the slit eye stone. A window in the vicinity of the teleporter column will be smashed (by barons from the other side?), jump through. You can try to land on the well with the supercharge. There is no escape from here but the door leading to the exit teleporter.
