Ultramarine is a take on a rhythm game where you protect a small submarine exploring an underwater trench from dangers lurking in the dark. The player is tasked with listening after a specific sound in the music which corresponds to enemies showing up, determining which direction the sound came from in their headphones, and scaring away the enemies by shining a light in the corresponding direction on the screen in time with the rhythm in the music. The game currently has one playable level which you can see in the video below.

Ultramarine was made as part of my bachelors thesis in music technology. Everything in the game was made by me! It's now available in its current form on itch.io (link at the bottom), but more levels are also planned.
