264:, the game does not allow the player to make moves which would lead them to be immediately killed. While defeating a single enemy is not a problem, tactical planning is essential for winning fights with multiple enemies at once. This basic formula is altered in many ways: there are monsters of varying speeds, multi-tile monsters such as Ivies,

The player can use the negative curvature to escape situations which would be impossible to escape in a similar game in the
Euclidean grid. Specifically, any monster following the player will get farther and farther behind unless directly behind the player; this is because following an equidistant to

The game has many special modes, allowing the player to take on a specific challenge (Pure
Tactics Mode, Yendor Challenge), or changing a crucial aspect of the game (Chaos Mode where lands change very quickly as you travel, Shoot'em Up Mode which is continuous rather than turn-based and grid-based,

The world consists of 72 lands, each of which has a different theme, treasure, enemies, mechanics, and a magical power; the lands are usually separated by hyperbolic straight lines ("Great Walls") and change as one travels, thus allowing monsters and magical powers to interact between the different

Many challenges in the game would be trivial in a

strategies from being effective. New lands and magical powers are unlocked by collecting treasures, but on the other hand, the amount of monsters spawning depends on the number of treasures collected in the given land, thus making it impossible to grind indefinitely.

The main goal of the game is to collect treasures while avoiding being trapped by enemies. Other than simply collecting the treasures, there are several major quests to undertake (Yendor quest, Prince(ss) quest, Hyperstone Quest and the
