What is "flinthook"

Flinthook is an upcoming action platformer and roguelike indie video game by Tribute Games in which the player's character uses a grappling hook to traverse procedurally generated spaceships for treasure. The developers were inspired by "rogue-lites" including Spelunky and Rogue Legacy. They said that the grappling hook game mechanic was their hardest design challenge. The game was first announced in March 2016 and is expected for release in early 2017 for Xbox One. Early previews of Flinthook noted the accessibility and tightness of the controls. Digital Trends listed the game among the best in show at the June 2016 Electronic Entertainment Expo.
