Crystal Rain Forest V2 is an updated and enhanced version of Sherston's 1992 title Crystal Rain Forest, there was also a Crystal Rain Forest 2000. It is an educational title sold to schools, it teaches numeracy, problem solving, ecology and environmental awareness but most of all it teaches the LOGO programming language.

Crystal Rain Forest V2 is an adventure game in which the player must find a way to save the rain forest which is gradually being cut down and destroyed by the Cut and Run Gang. The gang are chopping down the trees in the planet's last remaining rain forest. The king, who realises the importance of the oxygen giving trees orders them to stop so they shoot him with a poisoned arrow. Now the king lies in a coma in the city hospital and the only thing that can save him are the magic crystals that can sometimes be found in the forest. These natural crystals are hard to find but Professor Roberts is developing a way to make them artificially with his computer.

The game can be played in Adventure mode in which the twelve puzzles contained within the game are played in the context of the story, or it can be played in Activity mode where the puzzles can be played and replayed in any order. All puzzles are solved by using Logo commands which in later puzzles are built up into short routines.
There is a teacher option to choose between the two levels of difficulty in the game , this affects some, but not all of the puzzles. There are also teacher options to configure the game and an optional Crystal Logo function which allows players to write their own logo programs. The game can be fully narrated and, if enabled, will voice the LOGO commands as they are executed.
