It stayed over a year in beta, but, finally, A Valley Without Wind has been launched and is now available on everything from Steam and GamersGate to the MacGameStore and IndieCity. What's more, the game can be bought for 10% off during its launch week and you can sample its procedurally generated, open world, side-scrolling delights with the help of this hefty demo.

As is always the case with Arcen Games, I would expect the rather brilliant and already impressively deep AVWW 1.0 to keep evolving for the next few years, until it probably becomes a huge and stunning Metroidvania-eqsue entity that goes on to consume the planet.
