The game mechanics of Montezuma's Revenge
Room TransitionTraversalWorld is navigated as discrete named locations; moving between them swaps the active room with no spatial continuity.
Scrolling MovementTraversalWorld scrolls in one or two axes as the player moves or time passes; player exists within an advancing boundary.
Contact DamageCombatTouching an enemy or environmental hazard deals damage to the player without any explicit attack trigger from either party.
Lives SystemResourcePlayer has a finite number of attempts; losing all lives resets progress to a defined point or ends the game.
Key LockProgressionA specific named item in inventory unlocks a specific named obstacle in a one-to-one correspondence; item is consumed.
Interconnected MapWorldWorld is a single persistent connected space; new abilities acquired mid-game retrospectively open previously inaccessible areas.
Each mechanic links to how to build it in Godot, with the retro games that share it.
