Rope Untangle (Tensio Physics Prototype)

Untangle the knots. Free the board. Experience butter-smooth physics.

Welcome to Rope Untangle, a satisfying and brain-teasing physics puzzle. Your goal is simple: drag the pins to empty slots and untangle the ropes so that no two lines cross. What starts as a simple knot quickly escalates into a complex web of tension and logic!

Features

Satisfying Physics: Ropes dynamically tense, bend, and react realistically without sagging.

Brain-Teasing Puzzles: Progress through increasingly tangled webs that require spatial logic to solve.

Minimalist Fake-3D Aesthetics: Clean, vibrant visual style designed for pure focus.

Frictionless Controls: Simply click/tap and drag the pins.

Developer's Note: The Tech Behind the Magic

Are you a game developer, tech lead, or just curious about game engines? This prototype isn't just a puzzle game; it's a mobile performance stress-test for Tensio, a custom Unity rope physics tool I am currently developing.

Solving complex rope collisions (Continuous Dynamic Tensioning) usually melts mobile CPUs. To achieve a stable 60 FPS on low-end devices, this project was engineered entirely around Data-Oriented Design:

Powered by DOTS: The physics solver runs on Unity's C# Job System and Burst Compiler, offloading the heavy spatial hashing and collision math to worker threads.

Zero Garbage Collection: The physics loop allocates exactly 0 Bytes of memory per frame. No GC spikes, no stuttering.

Fake 3D Shading (1 Draw Call per Rope): The game uses zero lighting calculations. The 3D volume, shadows, and overlap separation are achieved entirely through `UV.x` math in an Unlit Shader Graph.
