Before the game's release, a benchmark of "Time Leap" was released online on August 3, 2009. The benchmark program consisted of a short conversation sequence typical of the gameplay found in a visual novel and a real-time dance sequence used to evaluate the graphic capabilities of the player's system. "Time Leap" was first released as an adult game for Windows on December 27, 2007 in both limited and regular editions. The limited edition release, in addition to the game itself, contains a five hundred-page partial storyboard collection drawn by various artists such as Akio Watanabe.
