Abyss Run

A fast-paced 2D vertical platformer built in Unity. The core objective is to climb to the top of a deep well shaft within a strict 60-second time limit using precision jumping and a magnetic grapple mechanic.

All gameplay systems, custom sound effects, and 2D sprite assets in this project were made entirely from scratch by me.

Key Mechanics

• Magnetic Grapple: Pressing Left Shift or clicking automatically latches onto the nearest grapple point within range—no manual mouse aiming required. Releasing it launches the character upward while damping horizontal momentum to prevent slamming directly into walls.
• Wall Bouncing: Bouncing off vertical shaft walls consumes wall-jump charges, represented by simple HUD indicator dots. Successfully connecting to a grapple orb mid-air refreshes all charges.
• Speedrun Timer: The 60-second countdown only begins on your very first input (movement or grapple). When time runs out, the run resets automatically after a brief delay.
• Score Tracking: Keeps track of your best completion time, max altitude reached, and total win count using local save data.

Controls

• A / D or Arrow Keys: Move horizontally
• Space / Up Arrow: Jump / Wall bounce
• Left Shift / Mouse Click: Shoot and hold magnetic grapple (release to launch)
• R: Instant quick restart

Architecture Overview

The codebase focuses on simple, readable scripts with zero extraneous logging during normal gameplay:

• AbyssPlayerController.cs - Handles horizontal physics, floor checks, and wall-jump charges.
• MagneticGrapple.cs - Manages proximity anchor detection and upward boost physics.
• SpeedrunGameManager.cs - Controls the first-input start clock, endgame triggers, and high scores.
• AbyssUIManager.cs - Updates altimeter HUD, timer text, and the typewriter quote display.
• JuicyAudioManager.cs - Plays sound effects and scales audio pitch upward with consecutive air bounces.
• JuicyCameraFollow.cs - Smooth camera tracking that locks within the well boundaries and stops shaking when the game is paused.
