Only grabbed the Echochrome Gallery bundle this week (nothing else noteworthy - already got the JP ver of Rocket Knight last week which is a nostalgia murderer, and Price is Right is more DD shovelware).
suggest everyone to pick it up, it's simply beautiful. Huge, huge amount of playable stages in a huge grid-view set to the new piano remixes. Beautiful audio and beautiful visuals. I find this "jump in and play" approach a lot more motivating than the original echochrome. You can select a level in the huge grid, zoom in and out on them, or randomize what level you play. They put a noticeable amount of polish on this little product.
Anyone who was a fan of echochrome, and ideally has a nice HDTV and surround setup, must download the bundle ASAP (believe the Gallery is only downloadable if you buy the bundle, not the OST's separately).
