The Mirror Crack'd: Fractured
I could post a trailer for a big smashy, shooty game right now, but it's a thirty second trailer, at least fifteen seconds of which is probably logos. So, instead of letting that sort of thing addle your mind, why not muddle your brain-stew around with Fractured, a free browser game that will exercise your neck muscles. There's a lot of head tilting and neck craning involved in this puzzle platformer, as each single-screen level is separated into shards, some of which are skewed at uncomfortable angles and many of which don't actually connect to their neighbours. By the sixth or seventh level, I guarantee that you'll have made a noise a bit like this - 'G'whaaaaa?' - at least once. Play it and try to prove me wrong. Via Indiegames.com.
