The game mechanics of Glider PRO
Free 2D MovementTraversalPlayer moves freely in 2D space with no forced scroll; camera follows player position.
Physics MomentumTraversalPlayer movement uses accumulated velocity that persists between frames; intentional momentum management is a core skill.
Contact DamageCombatTouching an enemy or environmental hazard deals damage to the player without any explicit attack trigger from either party.
Linear LevelsWorldWorld consists of discrete stages played in a fixed sequence; stages are self-contained with no backtracking between them.
Each mechanic links to how to build it in Godot, with the retro games that share it.
