This is a minor update of the game 'The Kaiyō Mission’ (under development). The animations and visuals of some of the animals have been significantly enhanced, and several minor improvements have been implemented. Furthermore, certain key features for the next mission phase have already been prepared. The game can currently be played in two different mission phases on three levels that represent underwater plateaus of ocean worlds, including the Saturnian moon Enceladus. A third mission phase and a bonus level are being implemented but are not yet accessible. 

In the first mission phase, 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 second mission phase is undertaken with human deep-sea explorers, extending the previous mission phase based on the areas and species already explored… and beyond.
