Rollin DOS

Rollin is an arcade logic game written by Michael Riedel from SAV Creation and published by Ticsoft.

The object of the game is to maneuver a ball through a level in top-down perspective from start to exit. The ball follows the laws of gravity, momentum and conservation of energy. Levels are composed of tiles with various properties and effects. The game has a single player, two player in turn and two player cooperative modes. The controllers supported are keyboard, mouse and joysticks.

Five "episodes" (level packs) were produced, each having 8 levels with a distinct visual theme. Episodes 2+3 and 4+5 were released as Part 1 and Part 2, correspondingly, with 16 levels each. Episode 1 was released as freeware, officially named "friendware" and also known as Part 0, containing 8 levels.

The soundtrack in electronic music genre was composed by Karsten Koch. Each released Part contains a different set of in-game tracks and a common main menu track.
