Set in the 1990s, the story follows Alex Eggleston and seven strangers who came to know each other on the web and became the closest of friends, living their lives carefree.
Until the fateful day of April 4th, 1999, when a woman named Sammy Pak suddenly went missing.
That night following her disappearance, a video of her last known moments was uploaded online. All of the friends excitedly watched as she is pulled from an elevator by something otherworldly, and decide to investigate the truth for themselves. As he gathers companions seeking to resolve the truth behind her disappearance, Alex's search for the woman spirals into an epic quest with stakes higher than he could have ever imagined.
- The '90s: The game takes place in 1999. Allegedly.
- Action Commands: When a character performs an attack, an object related to their move will appear and the player has to time button inputs to boost their attack power.
- Anachronism Stew: Despite supposedly taking place in 1999, there's a number of things that contradict that. Examples include characters partaking in late 2010's fashion trends and slang, citing games released just a few years before 1999 (such as Chrono Trigger and Secret of Mana) as their "childhood," and, most infamously, a gravestone for Satoru Iwata— who was still alive and active in 1999— that states the real-life date he died.
- Art Shift: On the day the group heads to New York, the entire scenery and everyone else turn into still neon-drawings.
- Bittersweet Ending: Despite Alex's and everyone's best efforts, Proto-Alex succeeds in destroying their reality and Alex is left as the only survivor. Though Alex manages to obtain new help from another version of himself and his friends from another reality to finally destroy Proto-Alex, with the alternate Alex returning home and the original Alex deciding to stay in the Soul Space.
- Breaking the Fourth Wall: The very beginning of the game requires the player to input names and various things about themselves, even though none of it affects the game's characters. This information eventually becomes relevant as the player is addressed as an "Alex" from another universe, and the game uses the names they input earlier for the party members in the final chapter.
- Cut the Juice: How Alex finally destroys Proto-Alex and Essentia, by disconnecting their division.
- Despair Event Horizon: Alex slowly starts to enter despair as soon he learns about the world's inevitable destruction. As soon everyone and the world is destroyed, he starts to lose all sense of hope as his only companion Panda abandons him, only drifting through the Soul Space endlessly to the point he starts to forget himself. He only recovers after finding a world Proto-Alex hasn't destroyed yet and uses the opportunity to finish the job.
- Failed a Spot Check: The Ultima Mystical LP record had Vella's name and year release right on front of it, something that had to be pointed out to Alex.
- Hopeless Boss Fight:
- The first battle against a Soul Survivor.
- When you deplete the Proto-Comet's health, it remains in battle and proceeds to banish each party member.
- Proto-Alex is undefeatable and remains standing even if you've taken out all his HP. You actually need to destroy the statues behind him and then purposely lose the battle to progress.
- Improbable Weapon User: The gang uses hula-hoops, phonograph records, picket signs, and cameras to harm enemies.
- Jump Scare: Happens near the end of the trailer when Sammy's apparition appears on the screen.
- Mistaken for Prank Call: Alex shrugs off a mysterious message he received from an unknown voice that called his house.
- Mood Whiplash: A very serious cutscene revolving around Rory revealing that his sister committed suicide and his resulting trauma from the event is interrupted by a Golden Alpaca attacking the party and yelling "Lemonade!" over and over.
- Multiple Endings: At least three different endings, all of which are canon, have been confirmed to exist by the development team.
- Purple Prose: The dialogue, starting with Alex's inner monologue, can get needlessly verbose.
- "Shaggy Dog" Story: Every prior plot thread goes unresolved with the destruction of Alex's reality. At the end, Proto-Alex claims that everything was a lie from Essentia to get Alex into a position to defeat him.
- The game has Alex mention a number of popular games that were his childhood... that also came out only a few years before the year the game canonically takes place.
- There's a bar that has a bartender named Jill that's clearly an expy of the main character of the same name in VA-11 HALL-A...except she doesn't act like VA-11's Jill in the slightest, making it come off as shallow. Turing (as in the actual Turing themselves rather than an expy) can also be seen standing on the counter, oddly enough offering Hassy despite their issues with it in their home game.
- The Soul Survivors look a lot like the Starmen from Earthbound.
- Unexpected Gameplay Change: A few moments sometime shift to an 8-bit platform.
- Every action in the game is a long, drawn out minigame.
- World of Weirdness: The otherworld has bizarre sightings, with some leveling on Acid-Trip Dimension.
