Entity

Right, after wandering around at the beginning without knowing what to do, I had a look at the competition entry notes, and realized a couple of things I suspected. Firstly, as per the instructions, you have to collect all 4 photos scattered in the map. But you soon notice that your energy bar is decreasing. Then you might notice that it recharges when you're around people. But, stick close to them too much and something that looks like skulls accumulates above your energy bar. Get 4 of those and you're dead. Also you can drop your aura and you can use that to recharge your energy, without the need for people. But you have to collect some pictures first.

Lovely gfx, interesting gameplay once you get the hang of it.
