This is an update of the first published version of the game 'Enceladus - The Kaiyō Mission' under development. It contains one level that represents an underwater plateau of the Saturnian moon Enceladus (additional levels and mission phases are being implemented but not yet accessible). The player has the mission to steer a solar-power-driven, robotic submarine and to identify and take pictures of underwater features, plants and animals. 

The game can now be played in German as well as English, the informative, optional guidance has been replaced by a proper, optional tutorial, new underwater features have been added, the sound effects have been fine-tuned, and the brightness setting as well as several minor improvements have been implemented.
