Amaltheia the Horsca

You choose to go through the left door. A little nervous, you hesitate before entering the room. How strange... This room is completely purple. It's near impossible to tell where the door is. However, in the middle of the room you see an opening. You quickly approach it and peer down. It looks to be a set of stairs, though you can't tell where they stop. What do you do?

Go down the stairs | Look for another door | Go back to the first room
