Gameplay consists of a side-scrolling world covered in 24 different kinds of crystalline flowers resembling gypsum flowers. The player controls an embryonic animal as it grows, survives and reproduces through 20 generations. Difficulty is introduced through the lack of instructions in the game. As such, the player must employ trial and error techniques to determine which flowers are edible, which flowers shrink or grow when stung, and which flowers are fatal or explosive when touched. The player may use either the organism's tail, stinger, or wings to bump or otherwise make contact with them. To maintain the challenge, the behaviour of the flowers changes every time the game is played. To increase the challenge, the score is repeated all along the left and right sides of the scrolling screen. As the score increases, the animal avatar is forced to travel more and more closely to the sometimes deadly crystal flowers.
