You control a small ball-like being called Kulkis which is capable of changing his color and spitting an acid. The color of the acid is always the same as the color of Kulkis. You help him in his ultimate quest to destroy all blocks and collect all diamonds while avoiding hazardous enemies and solving puzzles. In order to destroy Square Blocks he has to spit the same-colored acid on them. And to change his color he has to spit the acid on Colorful Circular Blocks. However the enemies will make his work harder rather rather than sitting in one place and doing nothing, so be prepared hence there are also many logical puzzles and other things waiting for you.
