Cave Story

Cave Story is a 2004 Metroidvania platform-adventure video game for Microsoft Windows. It was developed over five years by Japanese independent developer Daisuke “Pixel” Amaya in his free time. Cave Story features 2D platform mechanics and is reminiscent of the games Amaya played in his youth, such as Metroid and Castlevania. After its initial self-published release, the game slowly gained popularity on the internet. It received widespread critical acclaim for many polished aspects of its design, such as its compelling characters, setting, story, and gameplay. 

Cave Story is considered by many as the quintessential indie game because of its one-person development team and influence on the video gaming world. Independent video game developer Nicalis worked with Amaya to port the game to WiiWare and DSiWare in 2010. An enhanced version, Cave Story+, was released for Steam in November 2011, and the original game was released for the Nintendo 3DS in October 2012 with added content. A 3D remake of the game, titled Cave Story 3D, was developed by Nicalis and published by NIS America for the Nintendo 3DS in November 2011.

Cave Story takes place within the cavernous interior of a floating island. The island is populated by Mimiga, a race of sentient, rabbit-like creatures. A particular species of red flower that grows in the island causes the normally peaceful Mimiga to fall into a violent frenzy when ingested. The island also conceals an artifact called the Demon Crown, which has vast magical powers. An army of robot soldiers was sent to the floating island on a military expedition, seeking to harness the Demon Crown as a weapon for wars on the surface.

These robots slaughtered the Mimiga indiscriminately in their search for the crown, but were defeated when the Mimiga decided to eat the red flowers as a last resort. Shortly before the game begins, Professor Booster, the Sakamoto family, and various assistants formed a scientific party to research the island, but they became stranded when their medical doctor, Fuyuhiko Date, managed to acquire the Crown; he then forced the expedition to search for the red flowers. The player controls the on-screen character directly using a keyboard or gamepad. They progress by navigating platforming challenges and shooting enemies with the equipped weapon. 

When the player collects multiple weapons, they may be toggled at any time with the press of a button. Defeating enemies may yield yellow triangular crystals, which give experience points to weapons when collected, hearts that partially restore their health, or missile ammunition. Weapons may be improved up to level three, but taking damage causes weapons to lose experience and levels. Health and missile capacity upgrades are scattered throughout the game world. The player also interacts with many non-player characters and objects while playing the game.
