heyy, it'd be my first time working on a game jam, but I might be interested in trying some composition/music production and sound effects. I've never worked on an actual project before but I've been making my own video game style music on and off for about a year or two, and I'd say I'm about amateur level now. I can try any style of music and effects, but I'd probably say my current style is most similar to that of Toby Fox, if that's what you might be looking for.
let me know if you're interested at all, I think it'd be a fun way to get some collaborative experience :]
