Abyssal Towline — asset credits Trench backdrop assets/trench-backdrop.webp Original artwork painted for this build with the image model (5 credits). Used as the title-screen poster behind the mission brief. Audio All sound in this game is generated at runtime with the Web Audio API — oscillators, filtered noise and a feedback delay. No audio files, no external libraries. Nothing to credit beyond the code. Fonts and interface System font stack (Inter / Segoe UI / SF). No icon packs, no CDN components: the HUD, joystick, gauges and depth radar are drawn with CSS and a single 2D canvas. Typeface note Body copy falls back to the visitor's system sans; no webfont is loaded so the first dive starts instantly offline. - Sounds from "Rpg Audio" by Kenney (CC0). https://kenney.nl/assets/rpg-audio - Sounds from "Sci FI Sounds" by Kenney (CC0). https://kenney.nl/assets/sci-fi-sounds - Sounds from "Digital Audio" by Kenney (CC0). https://kenney.nl/assets/digital-audio
