I love a good puzzle game. I buy those little metal Chinese puzzles whenever possible. My wife is still bitter from the first such 3D puzzle she bought me that I solved in an hour or so. Its just a function of how my brain works, and I really enjoy exercising it. As such, I'm very excited about tonight's release of Echochrome in North America on the PSN (on the Sony Playstation Network Store). Its a very cool 3D puzzle game based lightly on the work of Escher.
You basically have control of a 3D view of a simple line-drawn environment with one or more little figures walking around in essentially straight lines on it. There are obstacles and jumping pads and holes in the floor and gaps to cross, all without any direct control of the characters. The really interesting part is that the rotating of the image such that a path looks connected (because the gap is hidden by another piece of the foreground) causes th path to be connected, at least until you rotate it again. The same goes for hiding obstacles or for how jumping and falling work.
Tell you what, try Youtube for a video of it instead, it'll make much more sense.
Now you get it? A little maybe? Very cool, don't you think? Now here's the really cool part -- you can create your own levels in the game, then either share them with friends or upload them directly back to the game makers and let them possibly include your creation(s) in future (free) updates to the game.
