Its great, I loved taking Pictures!
Obviously the world is terrible, its just placeholder blobs after all. having the photo stuck on your Screen until you press T again also is pretty odd. It could maybe use some interaction in the World with the pictures, but I don't really know what, and it also doesn't necessarily need this.
If this had some cheap story attached to it, that you're out in the wilds just to take some nice pictures or something, a beautiful world full of hidden secrets and small dioramha kind of Things that you could take Pictures of, maybe a small cabin where you can rest once it gets dark and look at your taken Pictures for the Day in dim candlelight or something. I'd easily spent a few hours in this looking for nice places to capture.
Is orthello dead or why didn't you submit that to DD and a new Project instead?
*Edit: Also you can jump out of your Map, and theres a short hitch before picking up the Camera.
