The first of the dungeon’s three big chambers.

There are blue switches to either side of the door you’ve just come through. Each opens up a different route forward.

Shooting the switch on the right raises some stairs leading to the door at the bottom-right of the picture. You can follow that route to Page 7.

Shooting the switch on the left requires you to rearrange the room’s platforms. Walk to the far end of the raised path (as shown in the picture) and it will see-saw into a new position (there’s a picture on Page 6). You can now get high enough to shoot the switch and open the door at the bottom-left of the picture. Going through takes you to Page 4
