The game based on Berusky that is also available for Debian, though this is the enhanced 3D version. Berusky II is a game that challenges your visual/spatial thinking and the ability to find a way to resolve a logic task.
The entire game takes place in a 3D environment while you slip into the role of different bugs and lead them out of a maze. In addition to arbitrary turning and level zooming all logical plots happen in space.
In comparison to the first part, new logical elements, a simple linear story accompanied by comic series, various 3D environments, water surfaces and others have been added.
