Composer + sound designer here, taking one team this jam.
A roguelite is a specific audio problem: the loop has to survive being heard forty times in one session, and you need a lot of short SFX. That's the package I do, written for your game during the week- menu theme, seamless in-game loop, 8–15 SFX, engine-ready WAVs named for Godot import. All original, no AI.
I'm submitting an OST-jam entry today and can link here once it's live, if you'd like.
