🦍 Hooke's Law and Angular Momentum

Ape Sling is a procedural endless climber based on pendulum physics and elasticity. The character does not jump; they are pulled. The player shoots a grapple point, creating a tether. The physics engine simulates the tension in the rope (Hooke's Law: $F = -kx$). As the ape falls, the rope stretches, converting gravitational potential energy into elastic potential energy, which then snaps back to launch the ape upwards.

The game is a rhythm of connection and release. Releasing the tether at the apex of the swing maximizes vertical height. Releasing at the nadir (bottom) maximizes horizontal speed but sacrifices height.

🧠 Timing & Vector Prediction

Cognitive skills engaged:

Oscillation Prediction: The player must predict the arc of the swing. Hitting a wall ends the run (or bounces, depending on mode).
Reaction Latency: As the level progresses, the walls narrow and obstacles move faster. The "safe window" for shooting the next tether shrinks to milliseconds.

🎮 Mechanics: The Bouncing

Interactions with the environment:

Anchor Points: You can only grapple to the blue "anchor" nodes (or specific wall textures). Shooting empty space results in a fall.
Hazards: Spikes and fire move. You cannot remain stationary. The "rising lava" mechanic forces constant upward progression.
Combo System: Moving quickly and chaining swings without stopping builds a multiplier, essential for high scores.

🏆 Climbing Strategy

1. Short Tethers vs. Long Tethers

A short tether gives you quick, snappy control for dodging tight obstacles. A long tether gives you massive momentum but less control over the arc. Use long tethers for open spaces and short ones for "minefields."

2. The Wall Bounce

You can bounce off the side walls to reposition. This preserves your verticality while changing your horizontal position, useful for aligning a shot to a difficult anchor.
