Aw man, this is one of the best physics games I've seen, if only half-glimpsed in trailer form. And O the things these crusty, jaded eyes have had to clock their gaze on. A game in which gravity is so changeable I legitimately don't understand what is going on. That's Airscape: The Fall of Gravity [official site].
There's a free demo available over on Steam, which is the first six levels - and a full release scheduled for sometime this August, but really just check out the trailer. The game follows an octopus lost and stranded on weirdly curvaceous planetoids in which the laws of physics shift on a second-to-second basis, where liquid and matter coexist as equally sensible material for roads and where the differences between oceans and Space are negligible.
Airscape is the work of a group of industrious students - just four of 'em, in fact. Which just makes it all the more mind boggling. Watch below:
