!! [=HyperRogue=] contains examples of:

* YetAnotherStupidDeath: No matter how well the game is going, you're still a OneHitPointWonder, and it's all too easy to get killed if you stop paying attention.

* PuzzleBoss: Every enemy in the game, arguably. But in particular the Hedgehog Warriors, Pikemen, and Flail Guards, which [[DamnYouMuscleMemory cannot be attacked directly]] and are killed by moving across adjacent tiles.

You explore an infinite world with 66 different lands, each with its own enemies, treasures, and power-ups. The goal of the game is to find, and unlock one of the Orbs of Yendor, but you're free to ignore the main quest, and go for a high score instead.

** And of course, [[Franchise/CthulhuMythos R'yleh]], with its infinitely nested Temples of C'thulhu.
** Hyperbolic space has completely contraintuitive (for us) relations between linear size and area. For example: if you consider that an edge of the game's tiles is around 1 m long, then a circle of radius mere 91.6 m will have greater area than ''Earth''. And yet, any two points will be less than 200 m apart. And with radius of 152 m, you will surpass the surface area of Earth-orbit Dyson Sphere (2.8 x 10^17 km2). A circle with radius 1 km would then have an absolutely insane area of 1,65 x 10^140 (!!) km2.

** The description of Demon Sharks says that they are demons from Hell that fell into the water. Sure enough, if a demon follows you across...

You explore an infinite world with 47 different lands (44 in the free version), each with its own enemies, treasures, and power-ups. The goal of the game is to find, and unlock one of the Orbs of Yendor, but you're free to ignore the main quest, and go for a high score instead.

* Infinite: The mutant ivy in the clearing. The mutant ivy is an infinitely large monster who's center is infinitely far away. You aren't supposed to actually defeat, just try and take some of its apples.

* HumansAretheRealMonsters: If you look at the player's description, it says "This monster has come from another world, presumably to steal our treasures." This is fairly accurate, considering that monster are docile unless they see the player.

* OneHitPointWonder: The player, and all the monsters that aren't [[InvincibleMinorMinion invincible]].

* TheDevTeamThinksOfEverything: There are lots of unexpected reactions from luring monsters into other Lands.

** Flying or incorporeal enemies don't trigger the {{Temporary Platform}}s in the Land of Eternal Motion.
** Anything that creates fire will ignite flammable materials in the Vineyard and the Dry Forest.

* DamselInDistress: A Princess is held prisoner in the Palace and there is a sidequest to find and rescue her. (Female [=PCs=] will rescue a Prince instead.)

* CrazyJealousGuy: If you manage to save two Princes, they will murder each other until only one is left.

** Flying or incorporeal enemies don't trigger the {{TemporaryPlatform}}s in the Land of Eternal Motion.

** Most monsters trigger explosions in the Minefield when they step on a mine. Birds, however don't, as they fly. But if you kill a bird and it happens to be on a mine, the fall of its dead body will set it off. On the other hand, Ghosts also won't trigger mines, but if you kill them, there's no corporeal body to fall, so the mine won't be set off.
* DamselInDistress: A Princess is held prisoner in the Palace and there is a sidequest to find and rescue her. (Female PCs will rescue a Prince instead.)

* EquipmentBasedProgression: The only way to get stronger is to collect various magical Orbs. And their effects are temporary, too., so it's more like No Progression.

** Sandworms, Cthulu's Tentacles and Rock Snakes can't be attacked, but they'll die if they're lured into a corner with nowhere to go.
** Greater Demons can't be attacked, but when you LevelUp they become easily-slain Lesser Demons.

* GoldenSnitch: Originally the Orbs of Yendor gave 1000 points each. Every other treasure gives 1 point, and you'll usually have just over 100 by the time you unlock the Orbs. Eventually the Orbs were changed to give 50 points, so that they weren't such a game-breaker on high score runs.
* HubLevel: The Crossroads. Unusually, it doesn't teleport you to distant lands - hyperbolic geometry lets it get away with just having a lot of borders.

* OneHitpointWonder: The player, and all the monsters that aren't [[InvincibleMinorMinion invincible]].

* StalkedByTheBell: If you wait for long enough in one place - usually because you're surrounded on all sides by walls, or enemies that can't move enough to actually kill you - the game will spawn armies of ghosts to force a Game Over.

* TwentyBearAsses: Collecting ten of any treasure will allow magic orbs to spawn in that area. Some lands also require you to collect specific treasures before they'll unlock - to get to Hell, you need to collect ten treasures in each of nine different lands.

** Version 7.0 also adds Shoot-'em-up mode, where you have ranged attack, your movement (and movement of monsters) no longer needs to follow the grid, and the game plays in real-time, with most mechanics kept unchanged.

* JungleJapes: The Jungle. [[ThatOneLevel Disproportionately difficult considering that it's unlocked from the beginning.]]

* BreatherLevel: Any land where you haven't collected any treasure yet will spawn few or no enemies.
** The Crossroads is always this, since there's no treasure to collect until you unlock Hyperstones (which takes a long time), and it provides easy access to wherever you want to go next.

* ClingyJealousGirl / CrazyJealousGuy: If you manage to save two Princes/Princesses, they will murder each other until only one is left.

* GoddamnedBats: Eagles, native to the Jungle and Mirror Land. They move two steps for every one you take, and although they can't attack on the same turn as moving, they can very easily surround you if there's another enemy nearby. To add insult to injury, they can fly over holes in the Land of Eternal Motion, invariably sentencing you to a Game Over if you don't leave quickly.
** Also, Ghosts in Graveyard. They are faster than you because they can move in straight lines and you cannot (since heptagonal tiles are inaccessible). If you are adjacent to two Ghosts, you can't do nothing but run away on a predetermined path until you either luck out and get out of Graveyard or run into another monster and lose (which is far more likely). This was eventually changed so Ghosts wouldn't move next to each other in order to make it easier.

* SurpriseDifficulty: Because of hyperbolic geometry, the quests that sound very simple are the hardest. The last part of the Yendor Quest requires you to simply walk back the way you came - utterly impossible unless you marked the path in some way. The Grail quest is even harder: Walk to the centre of a large circle.
** [[InvertedTrope Inversely]], if you anger a swarm of Hyperbugs you'll find yourself facing as many as fifty enemies at once... all attacking from the same direction, so you can simply kill one after the other with no danger of being surrounded.

You explore an infinite world with 34 different lands (32 in the free version), each with its own enemies, treasures, and power-ups. The goal of the game is to find, and unlock one of the Orbs of Yendor, but you're free to ignore the main quest, and go for a high score instead.

** The Shadow appears occasionally in the Graveyard, and simply can't be killed. It doesn't seem all that interested in you, though - if you move away from it, it eventually wanders off.

You can buy it on {{Steam}} [[http://store.steampowered.com/app/342610 here,]] or get the free version [[http://www.roguetemple.com/z/hyper/download.php here.]] The free version is complete, but it's updated less frequently.

''[=HyperRogue=]'', by Zeno Rogue, is a {{roguelike}} game about an adventurer in a non-Euclidean world. Originally released under the name ''Hyperbolic Rogue'' in 2011, it was updated to ''Hyperbolic Rogue II'' for the 2012 SevenDayRoguelike competition. ''Hyperbolic Rogue III'' was based on that code, and eventually re-named to ''[=HyperRogue=]'' for the Steam release.

The game is set on a hyperbolic plane, which has a lot of strange geometric properties. A regular grid of hexagons and heptagons, triangles whose angles add up to less than 180 degrees, straight lines that seem to curve away from you, infinitely large circles. Returning to the same place twice is very unusual. The creator was inspired by [[Creator/MCEscher M. C. Escher]]'s hyperbolic tilings for some of the graphics.

All enemies can kill you in one hit, but most of them also die in one hit, so combat becomes a series of puzzles not unlike [[VideoGame/DeadlyRoomsOfDeath Deadly Rooms of Death]]. You can only be killed if a monster backs you into a corner, or if several monsters surround you.

You explore an infinite world with 28 different lands (20 in the free version), each with its own enemies, treasures, and power-ups. The goal of the game is to find and unlock one of the Orbs of Yendor, but you're free to ignore the main quest and go for a high score instead.

** Eagles are the only enemy that doesn't trigger the {{TemporaryPlatform}}s in the Land of Eternal Motion. Since, you know, they fly.

** Most monsters trigger explosions in the Minefield when they step on a mine. Birds, however don't, as they fly. But if you kill a bird and it happens to be on a mine, the fall of its dead body will set it off.

* ButThouMust: The game will prevent you from walking into an enemy's attack radius, or otherwise doing anything that would instantly get you killed. You only lose the game when [[{{Unwinnable}} all your options would instantly get you killed]].

* WhatCouldHaveBeen: Euclidean Mode shows how the game would play on a regular hexagonal grid, with none of the hyperbolic weirdness. This changes several things, making various parts of the game easier or harder and some areas completely unplayable.
