Strider is supposedly about an alien taking control over Earth, but since the first level says "Казахская ССР (http://en.wikipedia.org/wiki/Kazakh_SSR)", there are small red stars everywhere, and one of the bosses holds a hammer and sickle... well, we all know what this game is really about.

This TAS is an improvement of about 2 seconds due to various minor optimizations.
