Projects I've worked on, songs I've written, pictures I've drawn, etc: https://mattforce.carrd.co/#projects

I've done a lot of pixel art animations and have written a lot of different kinds of music.  I know how to write adaptive (dynamic) soundtracks and have used Godot to program them.  I can more or less create any tone you want to capture, either from reference or simply a description.  The link I've provided mostly has higher-resolution art, but I started out doing pixel art.

Full disclosure: I've only worked on long-term projects and have not yet committed to a game jam, this'd be my first time; however, I'm fully capable of completing music and sprites within the time-frame.
