The objective is simply to destroy all the green hexagonal tiles on each of the 100 levels. As you progress through the game, more types of tiles are introduced which make things more difficult and interesting (hopefully).

• The game is bundled with ~40 free soundtracks in tracker formats (s3m,mod,xm), collected from different sources.
• All credits belong to their original authors.
• You can change the soundtracks by overwriting files in sounds directory by your own "tracker" or "ogg" music.
