sitting on a tree as music plays and an object flies across the screen. The options screen configures the starting level, game speed, and music. The player chooses a starting level between 0 and 20 that determines the number of viruses to clear, and one of three speeds of the falling capsules. The player's score is based on the elimination of viruses and the chosen game speed, with bonus points for clearing more than 1 in a single line. Dr. Mario offers a multiplayer gaming mode in which two players compete in separate playing fields. Each player's goal is to clear the private playing field of viruses first. Eliminating multiple viruses or initiating chain reactions can add capsules to the opponent's playing field. A player wins a single game upon eliminating all the viruses or upon the other player's bottle filling. The first player to win three games wins overall. Development Dr. Mario was produced by Gunpei Yokoi, creator of the Game Boy and Game & Watch handheld systems. Takahiro Harada, producer of the Metroid series, was its designer. Its music was composed by Hirokazu Tanaka, and has been re-used and arranged such as in the Super Smash Bros. series. Re-releases Dr. Mario spawned several remakes and ports that were released on various Nintendo consoles. The original version's multiplayer portion was ported to two Nintendo arcade systems in 1990: the Nintendo VS. System (as Vs. Dr. Mario) and the PlayChoice-10. An enhanced remake of Dr. Mario was paired with Tetris in the Super Nintendo Entertainment System compilation game Tetris & Dr. Mario, released on 30 December 1994. This was re-released in Japan on 30 March 1997, as a downloadable game for the Super Famicom's Satellaview peripheral, with the name Dr. Mario BS Version. It was re-released again in Japan for the Super Famicom's and Game Boy's downloadable Nintendo Power cartridges. The NES version was ported twice to the Game Boy Advance: first in 2004 as one of thirty games in the Classic NES Series (Famicom Mini Series in Japan), then bundled with a version of the Puzzle League series in 2005 as Dr. Mario & Puzzle League, with updated graphics and new music. Nintendo Puzzle Collection and the Nintendo GameCube Preview Disc, both released in 2003 for the GameCube, can copy the NES version of Dr. Mario to the Game Boy Advance using the Nintendo GameCube – Game Boy Advance
