## Description

_Doctris_ is a puzzle game similar to Dr. Mario. The goal is to help Doctor
Smith get rid of malicious viruses that infected all the vials in his
laboratory. Dr. Smith keeps tossing pills into the vials, and the player’s
goal is to move and rotate the falling pills, which behave in a manner similar
to Tetris pieces. Each pill consists of two segments of one of three colors
(red, blue or green.) If three, four or five segments (depending on difficulty
level) of the same color are arranged in a line, they vanish. To get rid of a
virus, the player must include it in a line of segments of the same color as
the virus. On each level, the goal is to eliminate all of the viruses present
in the vial. There are three difficulty levels, which differ in the speed with
which the pills are falling, and the length of the lines that must be created.
