Block Blocker

> System_Overview

Block Blocker is an intentionally rage-inducing, high-stakes 2D precision arcade platformer built from concept to deployment in Unity. Featuring a literal 2D square block traversing pixelated, hazardous obstacle courses, the game pays homage to classic retro arcade cabinets with relentless difficulty and razor-sharp timing.

Originally developed during the Glitched 2025 GameJam where it captured 1st Place, the project was subsequently scaled with expanded course trials, qualifying into Stage 2 of Genesis 4.0 at Army Institute of Technology (AIT) Pune.

Built for Android and WebGL (Browser), Block Blocker features 3 distinct map courses across 3 unique tilemap environments, ergonomic customizable on-screen touch controls, and a brain-bending Negative Edge (Release-to-Jump) Time-Trial mode.

> Core_Mechanics & Mobile Architecture

• "Negative Edge" (Release-to-Action) Input Engine

  Implemented a custom input dispatcher supporting both standard contact triggers and release-on-up ("Negative Edge") execution. This psychological twist disrupts traditional reflex timing, demanding calculated release pauses to clear gaps.

• Visual Deception & Severe Fumble Punishment

  Designed courses packed with deceptive visual cues—platforms that appear solid but are hazardous, or safe zones that collapse. In Time-Trial mode, falling for these tricks results in a massive fumble, forcing the player to master pure memory over sight.

• Ergonomic Customizable Touch Layout

  Recognizing the precision required on mobile, engineered fully rebindable, customizable touch button anchors allowing players to adjust button positions, spacing, and scale for maximum ergonomic comfort across all Android aspect ratios.

• Cross-Platform Deployment (Android & WebGL)

  Structured the project architecture to deploy seamlessly across both native Android devices and WebGL for frictionless browser-based playability, ensuring locked 60 FPS performance during high-speed platforming.

> Code_Snippet: Negative Edge Input Dispatcher

// Negative Edge (Release-on-Up) vs Standard Input Controller (Unity C#)
public class JumpController : MonoBehaviour, IPointerDownHandler, IPointerUpHandler {
    [SerializeField] private bool isTimeTrialRageMode = false;
    [SerializeField] private PlayerMotor playerMotor;

    public void OnPointerDown(PointerEventData eventData) {
        // In Normal Mode: Jump instantly on touch down
        if (!isTimeTrialRageMode) {
            playerMotor.ExecuteJump();
        }
    }

    public void OnPointerUp(PointerEventData eventData) {
        // In Time-Trial Mode: Negative Edge trigger on finger release
        if (isTimeTrialRageMode) {
            playerMotor.ExecuteJump();
        }
    }
}
