In the realms of “games that wot you jump up in”, outside of Zub, Wire Hang Redux is probably one of my biggest loves. Fairly long in the tooth (2004, although based on a slightly older game) it’s nice to see it finally getting a new and slightly shinier update for 2012. I realise in this post-iThing world that this sort of game is very much done to death on handhelds but still, they’re not Wire Hang and I *like* Wire Hang.
Grapple your way as high as possible, don’t drop off the screen. It’s really quite compulsive. For a few pennies here and there on the Mac App Store or direct from Matt on the Windows box. (Also runs fine under Wine I believe)
