I really enjoyed my time with Cloudbuilt, and now the real thing is out this week on Steam. You can grab it for $19.99, but it's also 10% off this week to celebrate its launch. If you haven't played it before, it's basically a third person Mirror's Edge starring a character with a jetpack (and thus, more freedom of movement), with elements of shooting, and a kick ass artstyle.
It features over 20 levels, with a branching level design and map reminiscent of Star Fox, as well as online leaderboard support. Steven is currently playing through the live version, so stay tuned for a full review.
