I completed this game over two and a half evenings last week and while it was a pleasant enough way to pass the time it is not a great game by any stretch of the imagination. You play as a photographer sent to document a ruined building [which turns out to be inhabited by two rival spirits], but your camera has a flat battery throughout the game so you never actually photograph anything, [which is a shame as there are some nice bits of architecture I'd have liked to have photographed and had as extras when I'd finished, for desktop wallpaper perhaps] which is somewhat odd. Your character also carries a notepad but refuses to take notes so you have to have a pen and paper standing by to jot down a lot of info over the course of the game.
The setting of the game is fairly nicely done, pretty well rendered creepily atmospheric semi-ruins, and some rooms still in full original condition, though there is not enough continuity between the areas and there seems little reason for the level of decay in some areas compared to others, there is also no explanation given for the blood stains which you see about the place. In fact the is a lot of back story you are left to wonder about generally, you are definitely not left feeling you have the full picture about what has happened by the end of the game.
The game play is simple, wander round the deserted building, explore all hotspots which are fairly easy to find in most cases and solve puzzles, the puzzle themselves are of a nice level of difficulty, pleasantly challenging I found. The game says it has 'non-linear' game play but that isn't strictly true; you can't access all areas straight away by any means but it is less rigidly ordered than most games. You receive ghostly messages to explain what you need to do at near start of the game and regularly throughout which make it fairly easy to progress through the 'story', you are also occasionally 'attacked' by a ghostly presence which is never actually a threat, you can't 'die' in this game. Your character will not interact with anything other than documents, doors, switches and the puzzles, if a door is even partially blocked by a cardboard box, that's it, can't go through.
There are two ending to the game but you can't actually see that your choice has made any difference, both ending seem to imply that you will discover more on your next assignment, a possible sequel?
One thing that was already annoying me by half way though the introductory cut-scene/video is the dialogue [actually monologue, your character never speaks] which never, ever uses contractions making everything sound stilted and unnatural, it really struck me as peculiar and I sort of spent the rest of the game noticing it and saying 'How odd' to myself and 'come on, just one "I'll"' but perhaps that's just my pet niggle.
It's a fairly simple game, though really quite impressive for what is basically a two man project. In summary: good puzzles, so-so plot, stilted speech and pretty but not wonderful graphics.
