Reception
Iwaihime received generally positive reviews.

A game replay, also known as a demo, is a recording of a video game which can then be played back from within the game's engine. Game replays are created from the the logging and playback of game data, such as player input.

A number of websites allow users to upload replays of certain games so that other players can download and watch them, either for entertainment or improving their own skills.

History
In 1993, id Software released the first-person shooter game Doom, which featured the ability to record game replays. By recording player keystrokes and mouse movement to a "demo" file, other players could load the demo in Doom and view the replay within the game's engine. Being only a few kilobytes in size, Doom demo files were readily shared online during a period where videos, with their comparatively large filesizes, were impractical to share over the internet. In early 1994, University of Waterloo undergraduate Christina Norman launched the "LMP Hall of Fame", a FTP server that hosted a collection of Doom demos focused on completing player-imposed challenges, an early precursor to modern speedrunning leaderboards.

In 1996, id Software's first-person shooter follow-up to Doom, Quake, was released.
