Supposedly, this game is about an alien taking control over earth, but since the first level says "Казахская ССР" (Kazakhskaya SSR, Kazahkstan in Soviet), there are small red stars everywhere, and one of the bosses holds a hammer and sickle, I think we all know what this game is really about.

Selected quotes from author:
This game is, in my opinion, extremely hard and seeing it beaten taking this quickly and with so few hits is quite impressive. There were some points when I took a hit in order to increase the speed, but otherwise I avoided as many as possible.
