Sonic Advance

is a 2001 platform game developed by Dimps for the Game Boy Advance (GBA). It was the first ''Sonic the Hedgehog'' game released on a Nintendo console with '' Sonic Adventure 2: Battle'' on the GameCube, and was produced in commemoration of the series' tenth anniversary. The story follows Sonic, Tails, Knuckles, and Amy as they journey to stop Doctor Eggman from taking over the world. Controlling a character, players are tasked with completing each level, defeating Eggman and his robot army, and collecting the seven Chaos Emeralds.

Development began after Sega shifted its focus to third-party software development, due to the poor performance of the Dreamcast console. Sega recruited Dimps to lead development, making the game the first in the franchise developed by the studio. While ''Sonic Advance'' follows a similar style of gameplay to the Sega Genesis ''Sonic'' games, certain concepts and designs were reused from newer games such as ''Sonic Adventure'' (1998). The game has been ported to Nokia's N-Gage and Android devices, and is available on the Wii U via the Virtual Console in Japan.

''Sonic Advance'' received positive reviews for its graphics, character animations, and faithfulness to the original Genesis games, but was criticized for its short length and special stages. It was a major commercial success, selling 1.21 million copies in the United States and is among the GBA's bestselling games. The game was followed by two sequels also on the Game Boy Advance; ''Sonic Advance 2'' (2002) and ''Sonic Advance 3'' (2004).

Gameplay

''Sonic Advance'' is a side-scrolling platform game reminiscent of the original ''Sonic the Hedgehog'' games released for the Sega Genesis. Players journey through an island to defeat Doctor Eggman, who is attempting to capture its animal population to turn them into evil robots. Players select one of four characters, each with their own unique set of moves. Sonic the Hedgehog is fastest and can perform an "insta-shield" that protects him for a moment; Tails can fly or swim for a short time; Knuckles the Echidna can glide through the air, swim above water for a few seconds and climb walls; and Amy Rose can destroy enemies using a hammer. Except for Amy, each character can defeat enemy robots by jumping and curling into a ball, or by performing a spin dash on the ground to gain speed. By entering a cheat code, players can control Sonic while Tails runs alongside him, similar to ''Sonic the Hedgehog 2'' (1992).

The game takes place over six levels called zones. Each zone is split into two acts, where the player must guide their selected character past enemies and obstacles such as spikes and bottomless pits to reach the end in under ten minutes. Scattered around acts are springboards, boost pads, and golden rings, which serve as a form of health; players survive hits as long as they have at least one ring, but their rings will scatter and disappear after a short period. Players collect canisters that contain power-ups such as speed shoes, elemental shields, and invincibility
