Gambys

The game centres about an imminent ecological catastrophe created by humans, where the only one capable of saving the planet were small creatures called Gambys. Thought to be a myth, these creatures are revealed to exist. These protectors possess a magical crystal which has memories of what the pure Earth used to be like including animals and plants, and the only way to save the planet is to release these images to the outside world.

To succeed, the player needs to clean and repair these images, which have degraded over time. The game includes various minigames of old ZX Spectrum games including a version of Space Invaders. The game bears similarities to Lemmings, with each type of Gambys having unique abilities and requiring different types of food replenishment. Enemies include Destroyer that reverses player progress, the Ghost that obscures the screen the image, and Gamby Girl who makes the Gambys inactive.

Throughout the 1980s, hundreds of Portuguese games were created for the ZX Spectrum, but by the following decade this platform had fallen out of favour. With the lack of a video gaming industry in the country, press like Spooler and Mega Score proved to be vital in the production and dissemination of games, and some of the first commercial products were Gambys and Portugal 1111. (The Elifoot series including sequels Elifoot II and Elifoot 98 were also very popular in Brazil in the 1990s.) In a local industry where interactive experience product were successful, it was difficult to convince investors to finance a purely entertainment video game, these proved to be the only two Portuguese commercial CD-ROM titles between 1995 and 2004.

Gambys' development team consisted of people well-verse in creating games for the ZX Spectrum, led by Portuguese developer Rui Tito and Paulo Carrasco, the latter of whom had authored titles like Megatron, Moon Defenders, Mr. Gulp and Alien Evolution. After receiving positive game reviews, they began to experiment with game programming for the PC. They were joined by Kraal creator Carlos Leote as programmer, Luís Peres as artist (whose drawings inspired the plot), Nelson Russa as game designer and Jorge Mônica as music and sound designer; they were collectively formed Viagem Interactive, which was the internal game development team of their larger company called Portidata. Production began in Portimão, with the team led by Rui Tito.

Jogos80 determined that the two-year wait period between showing the game to the press and the eventually release both beneficial and detrimental to the project, noting that despite the game improvements, it seemed outdated and non-commercially viable upon release in an era of rapidly advancing technology. Livro Verde Sociedade Informação 1997 said it had a "simple interface and careful presentation".

According to Video Games Around the World, the game was very well received in Spain and Portugal.
