through another site I found out flOw is free for download today (may just for today, not sure) on the PSN.
Figured I'd pass the info along. I DLed it and it is neat, reminds me of the 1st stage of Spore. You are a little plankton like creature, as you eat other stuff you get bigger. At the end of the stage you unlock a new creature and you repeat.
It seems each creature has it's own unique way of getting the job done. The 1st one I played I was a flat-worm like thing, the 2nd was a Jelly-fish like thing that I could get to spin and it seemed to make it easier to eat other smaller creature and to keep my HP safe.
You use Sixaxis part of the ps3 controller, so you just tilt to move. Tap any button will make your killer dash.
Pretty simple and seems like a good game to play when you have time to waste.
