by Edwin Abbott Abbott. A free prologue can be downloaded here, and the full game can be purchased from the App store here.A Noble Circle contains examples of:
- 2-D Space: All the gameplay is on a two-dimensional plane, which is justified since Flatland is a two-dimensional world. Averted once Circle learns to jump.
- Addressing the Player: You, yes, you, are a character in this game. Mr. Circle is well aware of his friend, named "Human," who is helping him along his journey, and The Narrator is talking directly to you.
- Call a Rabbit a "Smeerp": Flatlanders call height, "brightness".
- Critical Existence Failure: Everything will kill Circle instantly, sending him back to the last check point.
- Does This Remind You of Anything?: Like the novella before it, the game contains a lot of commentary on classism, racism, and sexism, as well as on the modern video game industry.
- Endless Game: Once you finish reading the closing credits, you can keep scrolling through Sanctuary for as long as you like. There's nothing there, but it is quite peaceful.
- Everything Trying to Kill You: Everything will kill Circle instantly.
- Flat World: Everything in Flatland is one planck length tall. If you don't know what a planck length is, don't worry; the game will explain it to you.
- Heroic Mime: The only time Circle speaks, we hear about it after the fact in Abbott's journals.
- Ignorant of Their Own Ignorance: The citizens of Flatland, although it's more willful ignorance in the end.
- Living Polyhedron: All the citizens of Flatland (and, technically, Circle, as he is described as, "a polygon with infinite sides.)
- Meatgrinder Surgery: The "correctional" surgery that polygons with more than three sides are forced to undergo and that was botched with Abbott.
- Musical Gameplay: The Narrator is insistent you play with the sound on.
- If the laser puzzles are giving you trouble, try tapping on the upbeat of the music.
- No Item Use for You: There is no inventory or items.
- No Plot? No Problem!: The Narrator informs you at the very start of the game that there is no plot; this is a journey fueled by your own desire for discovery.
- No Sidepaths, No Exploration, No Freedom: There's no leaving the path (although you can tap backwards to see what you just did), but this is not necessarily a bad thing.
- Protagonist Title: Mr. Circle himself.
- Random Events Plot: Just because there's no plot, that's not to say nothing happens.
- Shout-Out: To A Dark Room.She imagines an alien visiting Earth for the first time, standing behind her."So let me make sure I understand this," says the Wanderer in a confused tone...
- Walking Spoiler: Abbott, the only other circle in Flatland.
- Worldbuilding: A lot of the early chapters are this.
- Time Skip: Near the end of the chapter, ≈≈A Friend≈≈.
- Top-Down View
- Training Stage: The free-to-download Prologue.
