This game was developed in a short period of time using our proprietary Tube Engine for the physics and some of the graphics. It's a bit like Flow crossed with PacMan and Pikmin.
The goal seems simple (stay alive as long as possible), but with the concept of decay and splitting, it gets more complex. Pay attention to what happens to your creatures. If they start to shrink without being attacked, split them to create two new ones, each half the size.
