Castor

## Description

_Castor_ is a falling block puzzle game similar to Columns. Stones consisting
of three blocks of varying colors drop down and have to be arranged in the
right way. Pressing the fire-button will rearrange the blocks that make up a
stone. At least four blocks of the same color have to be lined up vertically,
horizontally or diagonally in order to clear them. The more stones are cleared
at once, the higher the score. A level ends after a set number of stones
(which increases with every level) has been dropped. Every 10,000 points the
speed of the stones increases. If the stones reach the top of the screen, the
game ends.
