My hat goes off to Sony ...
when I first heard that they weren't going to do a UMD or DVD release of Echochrome in the US I was bummed, but now that it's launched, I'm glad they decided on digital distribution only for this set of not-so-identical twin games for PS3 and PSP.
At $10 each, the price is definitely right, and both versions have completely different levels, as well as level creation tools.
It's not every day that we get puzzle games that tread new ground ... and while this one has some roots in games like Lemmings, it's equal parts zen exercise, minimalist art project, and MENSA entrance exam.
Great stuff ... yet after only a day of tooling around in the world of Echochrome even though I WANT to, I somehow feel woefully mentally under-equipped to CREATE levels ... hopefully after I start completing some of the more advanced levels I'll have a better grasp on thinking in "M.C. Escher" style visual logic.
