InFlux is the equivalent of a drop-dead beautiful girl who charms you with her wit before tripping over nothing and falling down a flight of stairs.
I can't really describe the game--it's a weird mix of abstract puzzle-solving and gorgeous outdoor environments. The puzzles themselves are clever but never venture into crazy difficult territory. I do wish the game relied less on me accidentally coming across the solution rather than letting me look around and solve it myself. That said, most puzzles still give a very pleasing "aha!" reward.
Navigating the world that links the puzzles is, for the most part, pleasing, but the ball you play as controls awfully. Expect to fall off cliffs, get stuck in the level geometry, or lose control numerous times. Overall, the controls are sluggish and, at times, unresponsive, which hampers the experience when you're starting to get into the game. Also, the camera is awful, sticking to walls as you rotate puzzle chambers and generally being a nusiance.
The environments are large and a joy to speed through, and the game even gives a word-free story that is surprisingly well-paced. It's very weird to see a game like this not only include a story, but do it in a way that feels surreal and captivating, rather than forced in. For me, the drive to explore this beautiful world was what kept me playing, and the game rewarded me with jaw-dropping vistas and a beautiful ambient score.
In short, InFlux is GORGEOUS and a great buy for puzzle and non-puzzle fans alike, as long as you can put up with the awful controls. Also, the game is taxing on lower- to mid-range machines.
