Mobile developer NimbleBit has announced its next game, an action RPG called Nimble Quest. The game is coming to iOS and the Mac App Store on March 28, and an Android version will follow some time in April.

You steer a line of heroes with various powers to cut through enemies, increase your skills, and grow your party size. It looks a bit like the classic game Snake mixed with a rogue-like. The announcement also mentions the ability to join a Guild and compete with other players in specially timed Guild Quests.
