Progress: First screenshot
Still not much progress, but here is a screenshot:

The “fog of war” (light) is working quite nicely and I changed the gameplay a little: The player doesn’t need to colonize the islands, he just needs to find them.
About photos: Well, I made few photos (deskphoto, foodphoto, …) but for some reason when I plug my camera to my computer the camera shows the low battery sign and turns off automatically, but taking pictures works. Either there is something wrong with my camera or I need to charge all my batteries (and I’ve already tried four sets of batteries).
Do those sailors know they’re being followed by a UFO?
