A 2.5D adventure game where you control a magical baby coral, seeking to revive the ocean where he lives and was destroyed because of human action, by collecting bleached (lifeless) corals and then planting them to resurrect the coral reef and gain new powers. Once all zones are reborn, the only thing left is to find the Protector of the Ocean, a being capable of preventing the ecosystem from being destroyed. The magical coral, named Coralium, is capable of learning skills from other sea animals as he unlocks new zones to move through the ocean by defeating obstacles on each level, some are invader or natural predators, some other are man-made.
