New to the PlayStation Store this week is Sony Japan Studio's perspective puzzler echochrome, plus a fresh batch of downloadable tracks for Harmonix's Rock Band.

Inspired by the works of MC Escher, echochrome tasks the player with guiding a mannequin figure through a level by tilting and turning the environment to create a path, while breaking perspective laws to get from A to B.

Available for both the PlayStation 3 and PSP, both versions of echochrome are priced at $9.99. Both versions include 56 levels unique to their respective platform, making 112 levels in all for puzzle fanatics.
