Gameplay
Enigma consists of approximately 1000 levels, known as ‘landscapes’ which may be played in any order. The player controls one or more marbles using the mouse, and interacts with the landscape purely through the marble. Levels fall into two broad categories: Oxyd landscapes and meditation landscapes. Some levels may appear to fall into one category while actually being in the other.
Often in each level, apart from the introductory ones that introduce the game gradually to the player, each level either contains a puzzle, race or many hazards (which tax the player's problem solving/logical skills, dexterity, patience and speed; these factors determine the overall difficulty of the level) which the player must solve, win or avoid or risk making the level impossible to solve (in which the player must restart it) or risk having the marble sink, fall down an abyss, destroyed or crushed. This takes away one of the players lives shown in the form of spare marbles in the inventory. The level automatically restarts from the beginning when all lives are lost, with the Oxyd colours randomly shuffled again. Some levels even are/have mazes which the player must find his/her way through.
