Piyotama puzzles PlayStation Store

One of the highlights of Sony's press conference at the E3 Media & Business Summit was the unveiling of JapanStudio's Echochrome, a unique PlayStation 3 and PlayStation Portable puzzle game with an Escher-esque bent. While that game still doesn't have a release date, interested gamers can check out Piyotama today, another PS3 puzzle game from the developer.

Piyotama challenges gamers to hatch the eggs of Mother Piyo by lining up four or more of the same-colored eggs in a row. The game includes single-player and multiplayer modes, graphics in 1080p, Sixaxis tilt support, and global leaderboards. Piyotama is available for $2.99.

In addition to the game, video clips for a number of other games and some feature films are going up on the PlayStation Network today. Two new promotional clips for Heavenly Sword will be available, including a "making of" feature and the first of five animated episodes that will fill in the game's backstory leading up to its September release. Other trailers include looks at Disney Interactive Studios' first-person shooter Turok, theatrical releases 10,000 B.C., Fred Claus, and Superbad, as well as the Blu-ray release of Perfect Stranger.
