This is InFlux, a puzzle game with elements of platforming and exploration, where you step into the role of an alien sphere of some sort which crash-landed on a desert island. It's also a rather good-looking game, as evidenced by the above trailer.
Impromptu Games, the Australian group responsible, is currently hard at work fixing some last-minute bugs, and hopes to release the Windows version of the game ASAP, with the Mac version following suit in a few days. If you're interested, you might wanna keep an eye on the game's website.
