AvaGlide

AvaGlide is avatar-based title, developed by British indie studio Haiku Interactive and published on the Xbox Live Indie Games channel. It was released in 2010, and praised for its visuals and gameplay.
Gameplay.
AvaGlide uses a player's Xbox avatar in a series of hang-gliding minigames. Three minigames include navigating the glider through rings to collect points and time bonuses, hitting targets with crates dropped while gliding, and a course to collect as many points as possible. Multiplayer functionality is enabled.
Graphics rendering.
AvaGlide uses the SunBurn XNA Game Engine (by Synapse Gaming) and a professional physics library, producing detailed textures and real-time shadows. The physics engine enables smooth gliding, complete with wind gusts and speed regulation that add dimension to the challenges.
