Fluidity: Spin Cycle is a puddle based puzzle platformer for the Nintendo 3DS. It's available from the eShop.
According to the reviewer, "Platforming games really have to do something unique to set themselves apart and the folks at Curve Studios have done a nice job of that. I was surprised at just how easy it was to manipulate this puddle of water, but also how difficult it was to keep enough control over it to get five star ratings on each level. The 3DS has some really great games available through the eShop and Fluidity: Spin Cycle is another top tier game in that environment."
