Hook, Line and Thinker is a fishing puzzle game by RhythmLynx. The game was made with Pico-8, using the virtual consoles restrictions to create the classic Gameboy aesthetic of 128x128 screen and 8-bit colour palette. It has now been ported to the Defold game engine, to be built for Android and iOS devices. 

Hook, Line and Thinker was shown at GDC 2017 as part of the Defold booth. 

I create all of the audio in the Pico-8 console using it's 16-bit audio generator. For the music I went with the theme of classic video game underwater sound tracks, but with my own melodic variations used create movement in the pieces. I create 4 tracks for game which including:

Intro/menu music - This is a variation on a sea shanty style with modulated white noise waves;

2 different level songs - The first a leisurely piece for a smooth introduction to the game and the second progresses into a darker tone to emphasise the sounds of the deep ocean;

Boss level music - A fast paced arpeggio driven piece to mirror the more challenging puzzles of these levels, based on classic video game water music.

The sound effects were all created using the softer waveforms in Pico-8. The main goal was to make everything seem heavier sounding and like it was underwater, all while retaining the user experience and feedback from interactions in the game.
