This is a combination of a bunch of different genres. Abandoned photography. Street art and illustration. Multimedia and gaming.
Both the photography and illustrations are quite beautiful. But the most interesting, and sometimes frustrating, aspect is that it almost functions like a point-and-click game, having to find the spot or combination of spots to click to get to the next room. With some clicks, things happen, others just move you forward.
It is possible to navigate directly to each room without finding the right spots to click. On a Mac you hold down the command key. Not sure what key on a PC, perhaps Control? LINK
