The game mechanics of Adventure
Free 2D MovementTraversalPlayer moves freely in 2D space with no forced scroll; camera follows player position.
Room TransitionTraversalWorld is navigated as discrete named locations; moving between them swaps the active room with no spatial continuity.
Contact DamageCombatTouching an enemy or environmental hazard deals damage to the player without any explicit attack trigger from either party.
Inventory ManagementResourcePlayer holds a collection of discrete named items with defined slot limits; deciding what to carry is a meaningful choice.
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.
