About Goodnight,Plankton

Using a microscope quietly sitting in a school science room, observe tiny plankton. Raise your favorites, or collect them all to complete your encyclopedia — the choice is yours. Why not fill your storage box with your favorite plankton? 【Game Features】 ・Feed your plankton to keep them alive. Even if one weakens, feeding it again can help it recover — take good care of it so it doesn't die. ・Give each plankton a name of your choosing. ・Use the camera feature to save photos to your device. Adjust the brightness or use food to guide plankton into position for the perfect shot! ・Different plankton can be found in different locations. Go out and collect the ones you're after. ・The game includes optional in-app purchases, but it's fully enjoyable for free.
