Navigation:
Walking will be the mean for users to navigate in my world. I gave up the ideas of flying or teleportations because, although they seem really cool, these abilities will take away the identity as a human explorer setting foot on this destructed place. In another world, flying and teleporting by hotspots could distract the users and prevent them from exploring every inch of the space in my world.
On the other hand, walking fits my world quite well. First, there are so many buildings with stairs, rooms, and floors that users can explore. As they walk, they can feel the up and down motion as they walk on the stairs or feel the smoothness of the floor of a room. Second, this world is full of mysteries and opened to users to explore by themselves. They are not directed by hotspots to teleport or fly to a different because this will defeat the purpose of exploration. Instead, the users will have the freedoms to go to different rooms and figure out what had happened there.
Still, I might incorporate one or two pairs of teleportation hotspots to surprise users when they enter a very dark room. Users might not be able to find those hotspots by the end of the exploration.
Interactions:
As users enter mysterious rooms, they will find various objects, ranging from books to chairs to toys. There are a few possible interactions that could happen between the users and those items:
- when users touch an item, the item animates and tells a story of how it comes to be this way
- some items can be picked up so users can use them later to unlock a door or provide light in the darkness for example
I think this usage of various household items might be good narrative of the forgotten. No living soul is there to tell the story so let the animated do the telling. In addition to storytelling, exploring and putting pieces of those items together are like solving puzzles. This would hopefully further engage users.
