Fancy Pants Adventures

👖 Fancy Pants: The Physics of Flow

Fancy Pants Adventures is the definitive academic text on 2D Momentum Physics. Created by Brad Borne, this title revolutionized browser gaming by introducing Slope Acceleration. On Watch Documentaries Games, we highlight this game not just for its art, but for its engine, which simulates friction, inertia, and gravity in a way that encourages continuous movement (Parkour).

Unlike tile-based platformers (like Mario) where movement is snappy and static, Fancy Pants treats the character as a physics object with mass. You cannot stop instantly. You skid. You roll. You carry speed into jumps. This creates a gameplay loop centered on "Flow State"—maintaining velocity to traverse loops and vertical walls.

🧠 Biomechanics: The loop-de-loop

The game rewards conservation of energy:

• Kinetic Energy Conversion: Running down a slope converts potential energy into massive kinetic speed. The player must learn not to jump on the downslope, but to ride it out to maximize the launch at the bottom.
• Wall Interaction: Verticality is handled via wall-running, not wall-jumping. This requires holding the input direction towards the wall, contrary to standard platformer logic.

🎮 Mechanics: The S-Curve

The level design is built around curves, not blocks:

• Squigglies: Collectibles follow the optimal path. If you follow the Squigglies, you are usually on the "Racing Line." They act as a visual tutorial for the physics engine.
• Rolling: Pressing Down on a slope tucks the character. This reduces air resistance and hitbox size, allowing you to break through destructible walls and bowl over enemies (Spiders).

🏆 Speedrunning: The Bunny Hop

1. Preserving Momentum

Friction is the enemy. On flat ground, running bleeds speed. Jumping preserves it. Advanced players constantly hop to minimize ground contact time, maintaining the top speed generated from the last slope.

2. The Wall Kick

At the apex of a wall run, jump away from the wall to gain height. This vector addition allows you to reach hidden areas located in the dead space above the main level geometry.
