Mars 21

The web version is good for quick testing but doesn't feature the opening cinematic. Please download a PC standalone version (Windows, macOS or Linux) for the full experience.

Mars 21 is a cooperative platform game for 2 players on PC. Player 1 controls an astronaut moving on the ground and player 2 controls a flying Martian creature. The two characters have different abilities and the players must cooperate to finish the game.

The game was developed in 1 month as our first video game project for the Interactive Digital Experience curriculum at Gobelins (Paris). The setting of the game is loosely based on science fiction short story collection The Martian Chronicles by Ray Bradbury. The game was further polished over 2 months in parallel with the development of new projects.
