In short, this is a fun little waste of time.
In less short...

You won't get a great deal of replayability out of this. Aside from the few "potential angelic" levels (ones where it's possible to solve with less than the allocated splices, which may take redoing that specific level a time or two), and a few sticky ones that can be frustrating, you'll just blitz through in a few hours and shelve it. That said, it's engrossing, and you will easily lose those few hours in one sitting before wondering who fiddled with your clock.

It does have a tendency to dump you in the deep end: there's no tutorial, and new specials are simply dropped on the first strand of each sequence so it can be frustrating simply not knowing the tools to solve it rather than due to the puzzle's difficulty. That's especially true with the first special where you're not told to right-click to activate when you've been drag-dropping before, or when you first get two specials at once and have to intuit that the slightly shinier one will go first regardless of where you click. However, there's a finite number of specials, and only drag-drop and right-click as controls, so it's doable, just would be nicer with a wee pop-up first time to say "hey, do X and Y happens!" to make it a little smoother.

The graphics are pretty, and incredibly smooth for what it is. I do also like how uncluttered the screen is so there's nothing to distract from the puzzle at hand. The music and effects sounds, similarly, are non-invasive: nothing spectacular, but they're inoffensive and relaxing - and if I'm honest a little bit hypnotic, which feeds into the "I can't leave my chair until I do just one more strand" aspect of it - without being too elevator-muzak-y. Suits the game perfectly.

Only glitch I've found is that it does not like windowed mode, in fact none of the graphics show up so you just get a background, tinkly music, and bloops as you click blindly at the ninja-genes. Annoying, but not game-breaking, as long as you, y'know, play in not-windowed mode. To be honest, it's that enthralling that you won't really want to be tabbing out, it really is, despite those few ♥♥♥♥♥♥♥, a one-sitting-playthrough kind of addictive.

First off, one massive love for this is how the optional achievements are set up. They don't affect the story, so you don't need to worry about running off all side-quest style unless you actually care, but for those of us annoyed by wee grey boxes, they've made life so easy. The chapters within an episode have the number of optional photos got versus available listed, so you can hop to the part you missed something rather than having to play right through and hope you don't trigger something that'll skip it, plus the inclusion of a "collectable mode" where your choices and actions don't get saved when you replay the few minutes that you didn't spot a pretty bird or some such, all make it nifty to nab the couple you didn't get during a real playthrough without mucking up your progress. It's a little thing, and to many it won't matter a jot, but it does show that the developers actually put thought into how us plebs play as well as what we're playing.

For the game itself, I've only got episode one (and will be getting the rest, never fear!), but it is beautiful. It's not the kind of game that'll challenge you or have you stressing over quicktime events, but it has a story that'll draw you in, and so much optional stuff like notices on bulletin boards and randomers yammering about stuff that randomers tend to yammer about that's all inconsequential but really helps to develop a full and vibrant world with characters you can actually care about. Plus it's visually beautiful - which I suppose is a must for a game focused around a photography-geek - and there's been real thought put into both the diegetic and non-diegetic music. Everything flows together so naturally, that even the juxtaposition of the supernatural events is believable and the characters' reactions to it sympathetic and real.

As I say, it's quite relaxed for the most part, and quite heavy-handed with the cut-scenes, but even that is kind of a necessity for a game that's more like a movie or a book focused purely on driving plot and character development: there's no big bad to chop up with an axe, but there's oodles of drama and it's incredibly easy to get lost in that world. Perfect for a chilled out evening.

This thing is freakin' epic! No quit finished yet, hate having to go to bed, it's stupidly addictive, and OH MY GOD THE FEELS!

Awesome awesome wee game.

Stupidly addictive. Servers have wee hissy fits from time to time, but it's free, and even most of the paid guff you can 'rent' for an evening using points earned in-game (affordable even if you suck like me).

Nothing spectacularly different to any decent FPS, but does have more of a feel of Ye Olde CS than the likes of MoH & co., and the community so far is shockingly nice.
