Retro Paddle Duel

A fast 60 FPS 2D cyber table-tennis arcade duel for Linux inspired by Pong,
featuring custom-illustrated 2D sprites, true impact-offset angle reflection,
paddle spin transfer, rally speed ramping, predictive AI opponents, and
same-keyboard 2-player local versus matches.

FEATURES
- True Angle Physics & English Spin: deflection angle scales smoothly from
-55 to +55 degrees based on paddle contact offset, combined with vertical
paddle velocity spin transfer and progressive rally acceleration.
- 1P vs Predictive AI & Local 2P Versus: challenge a trajectory-predicting
cyber opponent across Casual, Arcade, and Turbo tiers, or battle a friend
using W/S against Up/Down keys.
- 3 Cyber Courts & Powerup Modifiers: compete across Neon Cyber Court,
Solar Bumper Arena (deflecting prism bumpers), and Cryo Spin Stadium
(curved spin-drift zone), with Speed-Surge, Giant-Paddle, and Shield
powerup orbs, 16-bit PCM WAV sound effects, JSON match records, CSV
export, and English / Vietnamese UI toggle.
