In Japan, the PSP version of Echochrome costs double that of it’s PS3 counterpart. You can grab the PS3 version for 1,800 yen ($17), while the PSP version will run you 3,980 yen ($37). While some might contribute this to needing to print discs and manuals, there really is another reason.

The PS3 version is technically called Echochrome: Jokyoku (Echochrome: Prelude in English). In this version, you’re only getting 50 puzzles. The full PSP version contains 100 puzzles with multiple modes, one of which has you avoiding walking over dark echoes. Don’t fear though, as both versions have Canvas mode for creating and uploading your own levels to the PlayStation Network.

The game is hard as hell, based on everything we’ve played so far. While at Sony’s Gamer’s Day, no one was able to get past level 8 or 9 on the PS3. So don’t feel like you’re missing too much if you don’t want to pick up the PSP version.

No pricing has been set for North America yet, but I’m expecting it to be somewhere close to that of Japan. We’ll keep you posted when more information becomes available.
