The flyer is certainly a visual reference to some cult movie that I just cannot recall now, and so should be the various shots in the intro. The title screen is from Kubrik's 2001, after all. I imagine that Akamatsu Hitoshi was given free rein to cram as many homages as he could, for this title. I think that Sima Tuna perfectly summed up the point: some of these late 1980s to 1990s games should contain dozens of visual references and "homages", though we may not recognise them. It's all good! Use references to show what new results can be achieved by building on past knowledge, I always tell my students. Just cite the references in the bibliography or it will be considered plagiarism, ahem

Not sure why they sandwiched an "SF quiz mini-game", but my geek 11 years old me found it funny. I do remember two guys spending their credits while arguing over the game's physics (BA students in the subject...), but I "forgave" them because they taught me stages 7-2 and 7-3 ("you're too young to like Star Trek, kid"). I think that this was already one of the last "tactical action" titles, wasn't it? Even if players actually have unlimited ammos. Such a shame: stages' design and generous i-frames for enemies having 2 HPs invites players to use bullets wisely. At least the "high speed dude" clearance label is a major motivator to keep it fast
