Adorkable: Usol from Replay is a (comparatively) small creature that is nothing but nice and helpful to the protagonist.
Alas, Poor Scrappy: Mothra is difficult to play as and generally useless, and the narrator repeatedly complains about her. Even so, it's damn hard not to feel bad when she gets eaten by Red. Thankfully, she comes back.
The same could be said for Face. He was kind of a jerk at times, and a lot of the questions he asked were... disturbing, but Zachary admits to feeling sad when he suspected Face was going to die soon. Which he did in Zenith. But he also comes back at the end.
Awesome Art: He made those sprites himself. All of them.
Special mention goes out to Red's skull-shaped fire breath attack.
Awesome Music: Author decided to compose a bit of the game's music, and boy, what he did was awesome. He even seems to have Invoked this trope, in that he also referred to a bit of other music on the page for the stuff he didn't do.
This fanmade OST for the sequel, which is being used in a dramatic reading by the composer. SIN especially is fitting, and it even gives Usol a theme of his own! Even better; it's listed as a volume 1 due to the story being incomplete. There's gonna be more.
Big-Lipped Alligator Moment: The TV screen icons each display a brief, surreal animation that have little, if anything, to do with anything else in-game.
In the sequel, a creature waiting at the end of one of the "Isolation Zone" stages does nothing except say that "the first man on the moon was an Ezekiel Zanderfruit" and then promptly end the level. Subverted, because the name "Zanderfruit" returns in the recent chapter as a password.
Cliché Storm: Hits a lot of familiar creepypasta notes. Unlike most creepypasta, though, this one is lavishly illustrated, so the old "photorealistic gore" cliché is rather more vivid than normal.
The writer does display an amazing sense for atmosphere as the first creepypasta goes on, and arguably even more so in the sequel. That, and the sheer amount of it, helps it stand out.
Godzilla Replay subverts the trope though. The new protagonist has actually read the original creepy pasta and has spoken to Zach and is trying to invoke the events again for some reason, so the dynamic is very different from most video game creepypastas. However, things get even weirder, as demonic possession isn't apparent, and the game seems to have morphed into this weird sci-fi Mind Screw experience with some similarities to an in-universe ARG that Carl is trying to navigate. And this is on top of a weird Gotta Catch Them All objective of beating the incarnations of the seven deadly sins. The only cliché that stands out is Carl getting obsessed with the game—collecting the crystals from those incarnations in particular—and even then, the roots of this obsession seem like they might be deconstructed later on; the significance of the Seven Deadly Sins theme to Carl is still unclear, and the words of the minion who captures Usol imply that Carl is checking out this supernatural game because his "real life is worthless".
Complete Monster: Red, or the "hell beast", is a shapeshifting, sadistic demon who takes the form of a character in Godzilla: Monster of Monsters. After Zach, the player of the game, begins to get suspicious about the content in the game, Red reveals himself as a sentient monster within the game itself who directly threatens Zach. Red taunts Zach that his girlfriend's suicide was his doing, and that he is now torturing her soul. From there, Red engages in a brutal massacre, starting with the characters in the video game itself, then the angelic figure guarding Zach and the other figures aiding him, and ending with an attempt on Zach's life in the final battle. He paralyzes Zach and forces him to play the game and beat him or else die and have his soul trapped in the game.
Faux Symbolism: Acacius, the 11th-Hour Ranger who shows up to fight Red at the very end, shares a name with an Armenian saint who led the ten thousand martyrs, a group of Armenians who converted to Christianity and were then crucified. Although there are plenty of other Acaciuses the name is more likely a reference to. See Meaningful Name on the main page—the running pattern among the various famous people named Acacius is actually pretty relevant.
Forced Meme: "STILL THE BEST 1973" has absolutely no meaning to the story—the author just put it in in the hopes that it would become a meme. It did.
Genius Bonus: In Godzilla: Replay, Carl is unfamiliar with many of the more obscure Godzilla creatures. For example, in the Lost Way part, he ends up escorting Gorosaurus out of the level, while referring to him as "this blue dinosaur".
The end of the Blood Lake stage builds up a great deal of suspense for the boss. First a half-minute long screen reading "Mother" appears, and then the player finds the corpse of a pregnant creature hanged from a bramble patch by a spiny umbilical cord. Soon afterwards, its abdomen messily explodes to reveal a bat-like creature... with a clown nose and matching makeup. Named Bobo. It still manages to put up a good fight, though.
The boss of the "Organic" level, as well. The level leading up to it is quite freaky, with the hyper-realistic graphics turned Up to Eleven and all the monsters looking like skinned, misshapen animal corpses. The boss of the level? Can easily be described as a dog skull attached to a sausage.
The story itself has typos galore, indulges in creepypasta clichés like "hyper-realistic graphics", the game threatening the player directly, and the game physically compelling the player to keep playing, and the plot swerves from "this cartridge has something wrong with it" to "I have to save the soul of my Troubled, but CuteBroken BirdChildhood Friend from an evil demon who's also got it out for me" and suffers from a lack of foreshadowing during the switch. On the other hand, the custom sprites are just that good, so if one finds the story Narmy one can just enjoy the inventively unsettling sprite work.
In the beginning of chapter 6 the quiz asks Zack some disturbing questions, asking if he's ever raped someone, if he's ever been molested and... "Will you miss me?", which is the one that disturbs Zack. Possibly justified, as Face has asked Zack disturbing questions like the former two in each quiz level so far, but the last question (which usually refers to the game itself) is something ominous which he has no context for.
Once Red starts talking, he becomes a fair bit less intimidating - especially considering that a lot of his dialogue, with both the protagonist and the other characters, seems like it's out of a corny anime.
Narm Charm: The original story, as stated many times, falls into many creepypasta clichés and pulls several Shocking Swerves that can make it hard to take seriously at times. However, the sheer amount of effort put into the NES-style sprites and overall aesthetics allows quite a few people to look past the generic plot and enjoy it for what it is.
The Organic Level. It's even implied that this was the feeling Zachary got from the level as well.
In general, a common way the game manifests just how off it is is by displaying graphical capabilities that the NES wouldn't be able to handle.
Win the Crowd: Video Game Creepypastas are almost widely disliked and mocked by hardcore Creepypasta fans, given that a number of them are Cliché Storms that follow the same formula. Even though the story does include a handful of clichés, a lot of serious Creepypasta fans like this story because of how well-written and well-illustrated it is.
