Life on Mars Genesis [Megadrive]

Life on Mars: Genesis is a "MetroidVania", (a mix between Metroid and Castlevania - Symphony of the night) where you can freely explore the map, acquire new skills (double jump, run...) that will help you explore even more areas of the map, acquire and upgrade new weapons (grenade launcher, flamethrower), increase the capacity of your shield (health) and your power generator (stamina), etc.

This game is a reimagined adaptation of our previous release "Life on Mars" for the MSX2 computer and "Life on Mars Remake" for PC on Steam.
The setting is a bit like "Aliens" and other classic 80's sci-fi movies:

A scientific colony was established on Mars and frozen life was found in the Martian ice, a bacterium.
Shortly afterward, Earth lost contact with the colony.
9 months later, a ship from Earth finally reached Mars and a technician was sent to repair the communications array.
Playing as said technician, you must find out what happened to the colony.
