A high-precision, momentum-based cave navigator built with HTML5 Canvas.
- added second player networking
Rock's G-Force X is a modern reimagining of classic 2D cave-flyers. You pilot a scout ship through a massive
- In Air: Standard gravity pulls you down.
- In Water: Buoyancy pulls you up, accompanied by increased fluid drag.
- Move to the next level each time for a 1K Bonus and an extra life
- Gain a 10K Bonus for collecting all orbs in a level
- Collect Magical Orbs for 1K Bonus each
- Refuel/Rearm your ship on your home (starting) pad

High-Res Procedural Caves: A
$30 \times 30$ grid system creating massive$100\text{px}$ terrain blocks for a retro-tactile feel. - Smart Connectivity: Every cavern is processed with a Flood Fill algorithm to ensure no isolated "pockets"—if you can see it, you can fly to it.
-
Physics Engine: - Asteroids-style momentum (thrust adds to velocity).
- Dynamic drag constants based on environmental medium (Air vs. Water).
- Pixel-perfect tile collision detection.
-
VFX System: - Particle Explosions: Ship shatters into physics-based fragments upon impact.
- Dynamic HUD: Real-time depth tracking and environmental status updates.
-
Minimap: A real-time
$150\text{px}$ navigation suite in the corner.
- Language: JavaScript (ES6+)
- Renderer: HTML5 Canvas API
- World Scale: 3000 x 3000 World Units
- Performance: Implemented draw-culling (only tiles within the camera viewport are rendered) to maintain a smooth 60 FPS.
