Sony started up their Spring Fever last week with some excellent deals on PSN titles and the generosity continues this week with a couple puzzle games being put on sale. If you haven’t yet picked up echochrome or echoshift, now would be a good time to do so, as the prices are slashed in half. Down to $4.99 from $9.99 is echochrome and the newer of the two, echoshift, is available for $7.49 instead of its regular $14.99 asking price. Pick them up while you can! As usual, this offer is only good for a week – it ends 4/7/2010.
