This is basically a first-person puzzle-solving game. The character/you are in a maze-like series of rooms and you need to find your way out of each room and into the next. Your means of doing this are a pair of glove that allow you to (telekinetically?) manipulate your environment. The entire strucutre seems to be composed entirely of square blocks. Most of these are white and inert. However, a few are colored red, blue, yellow, green, and purplish pink. These colored blocks each have their own ability and can be manipulated from a distance using your gloves. For instance, yellow blocks form stairs, blue acts as a springboard, red forms ledges, etc. There are a few other tools/features you'll encounter along the way. Using what you find, you need to progress from room to room through the maze.
Anyhow, that's the gist of it. Overall, I thought it was a really fun game. Some of the puzzles are laughably easy while others are maddeningly difficult. Most of one level is dimly lit or even dark in places. Overcoming the challenges brings a sense of satisfaction, especially since the game doesn't give much in the way of tutorial...you, the player, just have to experiment and figure it out as you go. My only complaint was that the game is pretty short -- I finished the whole thing in about 5 hours. But judging by the many achievements I've yet to get, I'm sure I missed a lot on the first play through, so hopefully there will be decent replayability. Long story, short: It's a fun game, and definitely worth buying (especially if you can get it on sale or as part of a bundle or something). Enjoy.
