Pixelotl can be moved with the [arrow] keys or [WASD]. Some of the colored balls have just enough elasticity to let you squeeze through, and running into the side of a ball is all it takes to climb on top of it. However, crawling and jumping isn't enough, so you'll have to use the [spacebar] or [shift] keys to give yourself a little extra gravity. This extra gravity not only gives you more weight (for plowing through balls), but can also affect certain balls in a specific way. Your goal is to make it from one portal to another, collecting keys and saving your friends along the way, all while looking absolutely fantastic in the latest Pixelotl fashions.
There are fifty-one levels to tackle as you rescue your friends from the evil stork, which sadly pass by rather quickly. Still, Pixelotl is a fun, simple challenge that will delight you from your first step on a blue ball to the last scene in which you discover the harrowing truth about the stork. Besides, we really shouldn't be recommending that you put your lizard into a ball pit anyway.
