SieuCa: Save The Ocean

In the game, the surface of the sea appears man-made garbage. They seriously affect the habitat of marine life and deteriorate the image of the sea.
The player's task will be to touch junk items and questions will appear randomly about geography knowledge, vocabulary or sentence structure. Completing the sea trash item will disappear.
The game will end when the player has cleaned up the trash in the sea, returning a fresh habitat for the creatures.
