Jumping Flash!

Jumping Flash! is presented in a first-person perspective. The player assumes the role of Robbit, a robotic rabbit, and can freely move Robbit in three-dimensional space and can rotate the camera in any direction. The top part of the screen shows the remaining time, the player's score, and a character named Kumagoro—Robbit's sidekick artificial intelligence who offers the player warnings and hints.

The top left corner of the screen shows the collected power-ups; the top right corner contains the radar showing the locations of objects including enemies, power-ups, jet pods and enemy projectiles. The bottom shows a health meter on the sides and the number of remaining lives in the centre. The player starts the game with three lives; a new life is granted once one million points are earned.

The game begins on Crater Planet and revolves around the story of an insane astrophysicist, Baron Aloha. Planning to make a large profit from his evil ingenuity, Aloha removes giant pieces of land from the planet using machines to turn them into private resorts. Aloha removes and hides the twelve jet pods that propel each world. Witnessing the destruction, the residents of Crater Planet call for help, and in response the Universal City Hall dispatches one of their agents, a mechanical rabbit named Robbit.

Robbit is ordered to explore each world to retrieve the jet pods, stop Aloha, and save Crater Planet from destruction. At the end of the game, Aloha flees to his home, Little Muu, and vows revenge on Robbit.

Jumping Flash! was developed by Japanese developers Exact and Ultra. , utilising the same engine and some gameplay designs. After seeing Geograph Seal and realising the potential in their game design, Sony's director of entertainment in Japan, Koji Tada, paired Exact with Ultra to develop a new game for the upcoming PlayStation console.

Tada replaced Hiroyuki Saegusa as director of the game, although he had kept all key Exact staff to work on the project. Sony Computer Entertainment hoped Jumping Flash! would be remembered as the first appearance of a new "platform star" with the same longevity as Sonic the Hedgehog or Mario. The game was first revealed in early 1994 under the provisional title "Spring Man" as a technology demonstration for the upcoming PlayStation console.

The game received generally positive reviews upon release. Critics mainly praised its unique innovation, advanced graphics, gameplay and clean textures. The four reviewers of Electronic Gaming Monthly gave it their "Game of the Month" award, citing the outstanding graphics and particularly the innovative 3D gameplay. They described the style as "cutesy" but not off-putting.

"Major Mike" of GamePro said that despite the game appearing "strange", it had action, strategy, and some humour. Next Generation said that "[many] of the boundaries have been redefined in a big way", contrasting it with side-scrolling platformers with a first-person perspective and explorable 3D environments. They called it "simply superb" and gave it a "Revolutionary" five-star rating. Computer and Video Games magazine called it "one of the most innovative and entertaining games seen" and "the first true 3D platformer."

, including one spin-off. A direct sequel, Jumping Flash! 2—also developed by Exact—was released worldwide for the PlayStation the following year; it continued the story of Robbit and the subsequent rise and fall of Baron Aloha. The game received positive reviews upon release, with critics particularly praising its updated features.

Robbit Mon Dieu was released in Japan for the PlayStation in 1999. It was met with mixed reviews. Exact merged into Sony Computer Entertainment in 2000.
