This former Xbox Live-only title has been out on Steam now for a while - in both PC and Mac flavors - and I've played it for a bit. Not sure how far in, as there's no level changes or anything like that. It's just one seamless gameworld that scrolls mostly right-to-left as is the norm, with some up-and-down action too. 
I'm sure you guys have seen screenshots, it's a fully black-and-white game, set in a shadowy realm of horror and death - LOTS of death. ...And spiders. Holy crap, those spiders!
The hero is a small child-like figure with large, glowing eyes whom has to traverse this hostile landscape.
The graphical style is very clean and simple in a way, with a big cinematic angle; there's depth of field blurring foreground and background layers, the camera zooms in and out at times to adjust how much you're allowed to see of the surroundings, and there's a generous helping of film grain covering everything.
There's little details like low foliage growing along the ground, little pebbles tossed up by our hero's feet, and so on. The background often scrolls in parallaxed layers, which tweaks my nostalgia knobs something fierce, and everything is very nicely drawn. Some of the foreground graphics use quite low-res textures which looks a bit rough, but it's nothing worth complaining about really. Animation-wise, everything is superbly handled. Motions look realistic, but there's also a large dose of cartoonism infused in everything, balancing up the horror to some extent.
The gameplay is a cross between platforming and puzzle solving, often physics-based, and no fighting. Basically, anything you would fight in another game kills you in LIMBO, and you actually don't have any attacks at all. The closest we get is by using environment objects to defeat enemies, and many of these puzzles are quite clever. Some are quite frustrating as well, as timing becomes a more and more important element.
I've played LIMBO both on my PC - where it starts up in 2560*1440, the native rez of my screen - and also on my Macbook Pro with sandybridge-based Intel HD 3000 graphics. On my thunderbolt display (also 2560*1440, but I rather doubt that actually is the rez the game uses) the game runs rather smoothly; sometimes updates sag a bit when there's a lot of transparencies in use, but on the whole it's a wholly enjoyable experience and at no time did I die because of lack of hardware "oomph".
The game also syncs between game sessions using Steam cloud support (including between PC and Mac versions), letting you continue seamlessly where you last left off, regardless of which version you played last. This makes LIMBO a perfect game for laptop play when travelling or otherwise on the move!
The one issue I have with playing the game is the controls; you're stuck with either using arrow keys and Alt (on Macs) or Ctrl (on PC), or a gamepad to manipulate your little figure. It's a bit awkward playing with the keyboard, but I intend to buy a 360 gamepad. The wired Mad Catz MLG pad looks very interesting.
