Pendulum Rubber Action is a high-intensity, physics-based action game where you control a pendulum on a rubber string using mouse or touch movements to destroy targets. This work was created as an homage to the classic masterpiece "Pendulumania" by CANO-Lab / naruto.
- Mouse / Touch Operation: The rubber string's "anchor" follows your movement.
- Swing the Ball: Move the anchor quickly to swing the iron ball using centrifugal force and elasticity to hit targets.
- Destroy Targets: Hitting a target destroys it, adding to your score and recovering some remaining time.
The key to high scores is "how much you stretch the rubber" when you hit a target.
| Evaluation | Stretch % | Base Score | Characteristics |
|---|---|---|---|
| PERFECT | 90% - 100% | 1,000 pts | Maximum sparks and score |
| GREAT | 70% - 89% | 500 pts | High score efficiency |
| GOOD | 40% - 69% | 200 pts | Standard hit |
| OK | 5% - 39% | 100 pts | Light hit |
| FAIL | < 5% | 0 pts | No score added |
- Combo: Destroy targets within 5 seconds of each other to chain combos.
- Multiplier: For every 5 hits in a combo, your score multiplier increases (x2, x4, x8...).
- Large Score Notation: To handle astronomical scores, you can switch between "Kanji Notation" (Man, Oku, Cho...) and "Scientific Notation" in the settings.
Destroying specific targets will strengthen your ball or change the game state.
- 🟡 Yellow Target: Standard target. Recovers a small amount of time.
- 🟢 Green Target: Recovery. Increases the rubber's maximum load (durability) and recovers time.
- 🔴 Red Target: Weight Increase. Makes the ball larger and heavier, making it easier to hit targets. Recovers significant time.
Once you reach a 10-hit combo, special targets have a 15% chance to appear. Effects last for 10 seconds.
- ⚪ White Target (Kinetic Chaos): All targets on the screen start moving and bouncing off walls as if they have a mind of their own.
- ⚫ Black Target (Gravity Invert): Gravity is inverted, causing the ball and objects to "fall" upwards.
- Calibration: In the settings screen, you can fine-tune physics constants like gravity, elasticity (K), natural length, and collision bounciness to match your playstyle.
- Nostr Integration: Features a global ranking system using the Nostr protocol (Kind 30078). Sync your high scores to relays and compete with players worldwide.
- 3D Background: A cyber-space background rendered with Three.js that changes color and vibrates in sync with the game's tension.
This game aims to capture the tactile satisfaction of physics simulation and the beauty of high-stakes gameplay found in "Pendulumania," expressed through modern web technology.
