Hook, Line and Thinker
Hook, Line and Thinker (now known as Curious Fishing) is a fishing-themed puzzle game originally developed in the Pico-8 fantasy console. The project embraced Pico-8’s strict technical constraints, including a 128×128 resolution and limited 8-bit colour palette, to achieve a Game Boy–inspired aesthetic.
The game was later ported to the Defold engine for release on Android and iOS.
Project Overview
-
Developer: RhythmLynx
Platforms: Pico-8 → Ported to Defold (Android & iOS)
Showcased: GDC 2017 (Defold booth) -
I was responsible for all audio design and music composition during the Pico-8 development phase, working entirely within the console’s built-in 16-bit sound generator.
This required composing, synthesising, and implementing all assets directly inside Pico-8’s constrained audio environment.
-
Pico-8 presents several limitations:
Limited waveform options
Restricted sound channels
Tight memory constraints
8-bit aesthetic expectations
The challenge was to produce expressive, immersive underwater audio while remaining within these boundaries.
-
The soundtrack was inspired by classic underwater themes from early console games, while introducing original melodic variations to create progression and movement.
Four tracks were composed:
Intro / Menu Theme: Sea-shanty-influenced composition featuring modulated white noise to simulate wave motion.
Level Theme 1: A lighter, more leisurely piece designed to introduce players smoothly to early puzzles.
Level Theme 2: A darker tonal progression to reflect deeper ocean environments and increased difficulty.
Boss Theme: A fast-paced, arpeggio-driven track designed to heighten tension during advanced puzzle encounters, drawing influence from classic retro water-level music.
-
All sound effects were synthesised using Pico-8’s softer waveforms.
Design goals:
Create a sense of weight and depth to simulate underwater acoustics
Preserve clarity of player feedback
Maintain responsiveness within gameplay interactions
The emphasis was on balancing stylised retro sound with functional UX signalling.
-
Successfully delivered a complete, cohesive audio identity within strict hardware-style constraints
Supported the game’s retro visual direction
