Russian developer Sergey Obolonkov is putting the finishing touches on Jellyova: Open Sea Experiment, his undersea tribute to Sega's classic Ecco the Dolphin series.

In Jellyova, players control a giant jellyfish from an alien planet, which is able to switch the color of its core in order to interact with its surroundings. The game will feature Metroidvania elements, and Obolonkov notes that players will unlock new powers and abilities as gameplay progresses.

Obolonkov estimates that Jellyova is currently about 90 percent complete. A release date has not been announced.
