Your aim is to discover all the kinds of block at least one time. The game's got three game-modes: Free Mode (you have to discover all the environments), Time Challenge (you have not much time! Easy+Normal+Hard+Custom difficulties), Click Challenge (You have a limited number of element-uses on the blocks. Easy+Normal+Hard+Custom difficulties.)
You simply select one of the four elements, and click on a grassland block. The block and four adjacent blocks (in a + shape) will be affected by the element and will become a new environment block. (exampled: grassland blocks+water element change into woods). The mutated blocks can be affected by elements some more times, but the elements can be used ONLY on grassland blocks, and that's the difficult! :D (ex. Woods+water change another time and become "lake").
