Core Rules

1. Hop to an adjacent tile.
2. Crumble: The tile you just left crumbles into the abyss.
3. Trap your opponent to claim the island!

Key Features

• Game Modes: Play Solo vs Neural AI (Easy, Medium, Hard tiers) or enjoy Local Pass & Play (2P) with a friend.
• Aesthetic UI/UX: Soothing pastel Zen color palette, responsive 9-slice vector assets (PastelUI), and custom Pixeloid typography for a polished look.
• Dynamic Game Feel (Juice): Features organic, humanized AI thinking delays, tactile haptics, pooled spatial SFX, and procedural DOTween camera and tile animations for an immersive experience.

Technical Architecture & Engineering Highlights

• On-Device Neural AI (Unity Sentis):
  • Architecture: Multi-Layer Perceptron Regressor (MLPRegressor via scikit-learn).
  • Inference Pipeline: Trained model exported directly to .onnx and executed on-device using Unity Sentis / Unity Inference Engine.
  • Input Representation: Encodes current normalized board tile occupancy, relative positions, and adjacent degrees of freedom into a flat feature vector.
  • Decision & Difficulty Calibration: Output predictions drive move selection with tiered logic:
    • Easy: Probabilistic error injection with fallback neighbor hops.
    • Medium: Temperature-scaled sampling over valid tile probabilities.
    • Hard: Strict Argmax/Greedy selection of the model's highest-confidence output.
• Zero-Allocation SFX & Object Pooling: Memory-safe audio management with pitch randomization and zero Garbage Collection (GC) spikes during intense tile destruction loops.
• Mobile Performance (60 FPS Locked): Highly optimized URP pipeline including tight shadow cascades, 4x MSAA, disabled HDR, and zero-latency touch raycasting with UI bleed prevention.
