Deepest Sword

⚔️ Deepest Sword: Fulcrum Mechanics and Torque

Deepest Sword is a physics puzzler that reimagines the sword not as a weapon, but as a Locomotion Tool. Hosted on Watch Documentaries Games, this title explores the physics of Levers and Fulcrums. The protagonist cannot jump. Instead, they must use their sword to push against the ground, vaulting over obstacles. As the game progresses, the sword grows longer, changing the physics parameters (center of mass, rotation radius) of the puzzle.

The game is a spiritual successor to "Getting Over It," testing the player's patience and understanding of Torque ($$\tau = r \times F$$). A longer sword allows for higher reaches but requires more space to rotate, making tight corridors a nightmare of geometric positioning.

🧠 Cognitive Physics: Rotational Geometry

The player must constantly calculate rotational arcs:

• The Vault: Placing the tip of the sword on the ground creates a pivot point. Rotating the character creates lift. The longer the sword, the greater the potential lift, but the slower the rotation speed (Moment of Inertia).
• The Jam: In narrow tunnels, a long sword gets stuck. Players must visualize 360-degree rotation to untangle the blade from the geometry.

🎮 Mechanics: The Growing Blade

The difficulty curve is tied to the sword length:

• Variable Physics: Stage 1 sword is a dagger (agile). Stage 5 sword is a pike (unwieldy). The player must relearn the movement physics after every boss encounter.
• Stabbing: The sword must penetrate the dragon's heart. This requires aligning the blade perfectly with the target while dealing with the awkward momentum of the body.

🏆 Mastery: The Pogo Technique

1. The 360-Spin

To climb vertical shafts, you must master the continuous spin. By rotating the sword rhythmically against the walls, you can "walk" up the shaft using friction and leverage.

2. Tip Control

Precision is key. Place exactly the tip of the sword on the ledge. If you place the middle of the blade, you lose leverage height. Treat the sword tip as your foot.
