This is nicely done. Did you write this one? BTW on Mathematica 10.1 "Restart" did not do anything - I could not shoot. But otherwise this is a cool idea, indeed Arcade games are awesome.
Raiden ( ?? ) is a 1990 scrolling shooter arcade game that was developed by Seibu Kaihatsu. It was the first game in the Raiden series of scrolling shooter arcade games. Raiden was released in September 1990. The game was distributed in Japan by Tecmo, North America by Fabtek, Taiwan by Liang HWA Electronics, Korea by IBL Corporation, Hong Kong by Wah Yan Electronics, and a few other countries such as Malaysia, though the publishers in those countries are unknown.
Due to the success of Raiden, several sequels and related games were made. ~ Wikipedia
