Tails Adventure is a platform game developed by Aspect and published by Sega in 1995 for the Game Gear. The game stars Tails from the Sonic the Hedgehog series in a solo adventure, as he collects an array of items to help him explore Cocoa Island and defeat the enemies inhabiting it. The gameplay is more slow-paced than other Sonic games, with Tails only capable of walking and flying at a moderate speed. The stages are explored in a non-linear fashion, with newly collected items opening up pathways in previous areas. Along with Tails' Skypatrol, the game is one of two on the Game Gear to star Tails in a solo role. Tails Adventure received mixed reviews, with critics finding the game unoriginal and too slow-paced compared to previous Sonic offerings. Retrospective reviews commended the game for trying something different and compared the gameplay to the Metroid series, but disliked what they felt was repetitive backtracking. Tails Adventure was included in Sonic Adventure DX (2003), Sonic Gems Collection (2005), and re-released on the Nintendo 3DS in 2013. Gameplay Contrary to the classic speedy gameplay in the Sonic the Hedgehog series, Tails Adventure is a slow-paced platformer with an emphasis on exploration. The player controls Tails in a story set before he befriended Sonic, as he adventures to save Cocoa Island from an invasion of the Kukku Army. He cannot run, but only walk at a steady pace. The player explores twelve non-linear stages, collecting new items and abilities to open up new path ways in previous stages. A total of 26 items can be collected, including some to defeat enemies and others to aid in exploration. Along with using items, Tails can fly for a short period of time. His fly duration can be extended by locating Chaos Emeralds. Rings are collected as a form of health, and unlike other Sonic games, only a few rings are lost when touching a hazard. This gameplay has been compared to Metroidvania games. Tails finds several different kinds of gadgets on his adventures. Some of these items are weapons used to defeat enemies, like bombs and hammers. Some items aid in exploration, such as a small robot which Tails can control to scout ahead and squeeze into tight spaces. Tails can only carry four tools when entering a stage. Only one item can be equipped at a time, the player must pause the
