The purpose of the game is to destroy balls using a harpoon. When those balls are hit, they will split
into two smaller balls until they are totally destroyed. There are also some special balls which will
appear during the game.
Right after starting the game you will have a menu available, in which you will be able to select some
playing options. You can use cursor keys to navigate through menuoptions and use Enter to select one. 'P'
key pauses the game, and Esc quits.
In that menu, you can select the number of players (between 1 and 6), Select some game options, like turn
the sound or the music on and off, or switch between fullscreen, windowed screen or widescreen. You can
also select the keys for the players.
There's a tutorial available through the starting menu, that you can use to learn how to play.
