The trilogy is set in a not too-distant future when humans have started colonising space. For the first two instalments the player takes the role of Kim Kimberly, an undercover agent, whose goal in Snowball is to save the colonist's spacecraft from crashing into a star, and in Return to Eden to stop the defence system at the destination planet of Eden from destroying the craft. In The Worm in Paradise, the player, taking on the role of an unnamed citizen of Eden, must travel around the city of Enoch, learn its secrets, earn money and save the planet.

Gameplay

The games use a text parser

 more than a thousand words to control movement or actions. It looks at the command, picking out two or three words it knows, ignoring the order, and tries to guess what is meant. For movement, the usual commands for moving 'NORTH', 'SOUTH', 'EAST' and 'WEST' are available (and their abbreviated forms of 'N', 'S', 'E' and 'W') as well as 'UP' and 'DOWN' ('U' and 'D' respectively) and a number of other directions and 'modes' of movement (like 'JUMP'). For actions, it understands how to pick up objects, opening doors, lighting lamps, as well as dropping objects and wielding them. Additionally, there are commands to invoke 'SAVE' and 'RESTORE' of game positions to cassette tape or floppy disk (for some systems also to RAM), ask for 'HELP', turn off pictures and turn them on again with 'WORDS' and 'PICTURES' respectively, an 'OOPS' command to undo

Silicon Dreams can be played as three separate games, but to obtain a maximum score the games must be completed in order, carrying the score from one adventure to the next. Points are not scored for collecting treasures, but rather for doing specific tasks towards the aim of the individual game. In Snowball the goal is to get to the main control room and prevent the starship from crashing into a star. In Return to Eden the goal is to get into the city of Enoch and stop the robots from destroying Snowball 9. And in Worm in Paradise the goal is to find as much information about the city as possible, obtain money, and then become a member of the governing party of Eden, saving the planet in the process.

Setting

The trilogy is set in the future, when the human race is literally reaching for the stars. The entire Solar System has been linked together through accelerator chains, and the "Big 5" nations of Earth have set in motion a plan to colonise the galaxy. This is known as the Terran Expansionary Phase. It lasted ninety years from 2120 to 2210.

The first step was to launch probes into outer space. The probes reported any Earth-sized planet they encountered during their centuries-long voyage. Each probe was followed by a survey ship ten years later. The ship's mission was to map the planet and if it was habitable, it would signal Earth and then, while waiting for the colonists to arrive, terraform

 the planet.

This is the second step in the phase. The survey ship mined materials from asteroids and used them to build a robot factory in space — a process that could take decades. The resulting robots built more space factories that in turn produced better robots. They also built large satellite dishes to collect data sent from Earth containing the latest technological advances. Then the actual terraforming took place. The robots landed on the planet and built cities while also launching more probes and survey ships further into space.

Once Earth received news of a habitable planet, the third and final step took place. Ten giant passenger discs, each carrying two hundred thousand colonists in stasis

Whereas suspended animation usually refers to a greatly reduced state of life processes, stasis implies a complete cessation of these processes, which can be easily restarted or restart spontaneously when stasis is...

, were towed into space. Next came the engine unit, which was linked to the front of the discs, and then the colony ship was completed and ready to go.

During the 2190s fifty colony ships were launched from the EEC's Ceres base, among them the Snowball 9, which carried the first colonists for planet Eden on the Eridani A

 engines on the later part of the trip. This ice shell gave the Snowball series its name.

After receiving the last ice block, the crew put the ship in autopilot and went to hibernate with the passengers, leaving the ship's maintenance to robots. Except for a brief period of activity to start deceleration , the crew slept for most of the trip, waking up one year before reaching Eden. The plan was to continue deceleration while consuming the last of the ice shell, and then put the ship in orbit around the planet, delivering the passengers down by gliders that would be retrieved by hooks to be reused.

Kim Kimberly

The protagonist in the two first instalments, Kim Kimberley, is a tall, athletic, intelligent woman with brown eyes and fair hair. She was born and raised at Hampstead Crèche, which was closed when she was thirteen due to violations of the Android Protection Acts. She finished her education at the Milton Keynes School of Life in Malta, then returned to England for National Service

Snowball

Plot

As the Snowball 9 approached Eden, something goes wrong. A crewmember murders her shipmates, destroys the communication system and set the ship on a collision course with the sun. The robots, being little more than automata

, continue their everyday operations oblivious to the danger but the ship's computer, capable of thinking, wakes up Kim Kimberley before the deranged crewmember destroys it. She exits her modified stasis chamber with the goal of finding a way to reach the control room and avert disaster.

Development

Snowball was originally released in 1983 as the company's fourth adventure game using the A-Code system. Nick, Mike, and Pete Austin headed development. Though Level 9's previous games featured a fantasy theme, the Austin brothers chose a science fiction theme. The original release used version 1 of this system and was initially released only for the BBC Micro

 name." The debate came to an end with the release of Return to Eden, where it was made clear that Kim was not a man, because the surviving crewmembers confuse her with the woman who tried to destroy the ship.

Return to Eden

Plot

With the Snowball 9 orbiting Eden, the surviving crewmembers put Kim on trial. The only evidence against her is the "mempak" from the control room, which shows her as the hijacker rather than the saviour. Despite the fact that the recording is damaged and thus is unreliable, they sentence her to death. About to be thrown into space, Kim manages to escape aboard a "stratoglider" and an hour later, lands on Eden. At this point the game starts.

The first thing the player must do is find a shelter for Kim, because a few moves into the game the Snowball 9 crew use the ship's engine to try to burn her down. The native robots take this as proof that the Snowball 9 is not the ship they were expecting but a hostile alien craft they must destroy. The objective is to contact the robots before time runs out for the Snowball 9 and everyone aboard it.

Development

Unlike its predecessor, Return to Eden only had around two hundred and fifty locations, but it was Level 9's first game to feature graphics. Other adventure games had included graphics before, but version 2 of the A-Code system, allowed Level 9 to encode

 RAM. The user could choose not to display them and play the game in text-only mode. It was released for the same platforms as its predecessor.

The game's first cover depicted a robot fighting a monster plant in Enoch. The robot resembled a comic book character, so to avoid legal troubles, Level 9 commissioned Godfrey Dowson to do a new cover. Dowson's illustration depicted another robot in the jungle looking towards Enoch. Level 9 was not satisfied with the result and asked Dowson to do it again. They liked the third cover so much, they hired Dowson to do artwork for the re-release of their old games as well as for their future titles.

Pete Austin commented on the game: "It's an alien theme park

The Worm in Paradise

Plot

A hundred years after the arrival of colonists aboard the Snowball 9, planet Eden has become home to half a billion people. In this paradise run by robots there is no crime, no taxes, no unemployment, and no freedom. The population lives in domed "megapolis," and perhaps due to the war that took place during Return to Eden, there is no contact between the cities and the surrounding natural world. The occasional sighting of flying saucer

s keeps the population afraid from going outside.

The main character, a nameless citizen of Enoch, starts the game in a beautiful garden where everything seems fine. He picks an apple from a tree, a worm pops out, and the player follows it outside the garden, through the desert, and then he wakes up. It was only a simulation, one of the many forms of entertainment available under the reign of the third Kim. This "Garden of Eden as a prison" allegory sets the mood for the entire game. The objective is to explore the city, and while doing so the player must gather clues to unmask the government conspiracy behind the flying saucers.

Development

The trilogy's final installment is a departure from the previous games. It "evolved alongside a 12 month enhancement on Level 9's own adventure system. Standard features include a 1,000 word vocabulary, a very highly advanced English input, memory enhancing-text compression, the now familiar and very much appreciated type-ahead, and multi-tasking

 so a player need never wait while a picture is drawn." This was the first game using version 3 of the A-Code system. It was released for four fewer platforms, leaving out the Lynx, Memotech MTX, Nascom and Oric-1 compared to the two previous releases.

Another departure is that the player has only seven days, within the game's clock, to complete the game. Quests are also time-based and require that the player arrive at certain locations at specific hours to achieve the desired goal. And while gameplay remains the same, the backdrop is no longer an action adventure, but a political thriller

. Similar to what happened when Snowball was released, there was certain confusion about the main character's identity and the time when the story took place. The Level 9 Fact Sheet says: "...a couple of years later, Kim Kimberley has become a legend on Eden." Another article stated: "Worm in Paradise is set 100 years later. You are now Kim Kimberley III..." Furthermore, Pete Austin said, "Worm is set on Eden, about 50 years in the future" and "The player is not Kim - she becomes mayor and runs the place." Notice that these sources called the game by its original name, Worm in Paradise.
