The best I came with my last attempt to describe Nidhogg dev Messhof’s new (old) game Flywrench [official site] was “it’s like Kuru Kuru Kururin or Roundabout but not spinning and more a platformer but without platforms or Swift*Stitch with flopping and colours.” Honestly, I think I’d struggle to reach even that low level of usefulness today. That’s fine, though – you don’t need me any more.
Following a 2007 free prototype and a 2009 Kickstarter, the full version of Flywrench is finally out on Steam so you can see for yourself.
