That is absolutely fine, yes! For that matter, anything on my bandcamp is fair game as long as it’s under a CC license (and that’s most of it).

Crediting me as “fluffy” with a link to my website and/or the respective album page would be preferred.

You’re welcome to use any of my past music as long as it’s under a compatible license (I release most of it under Creative Commons), and yes I do commissions.

In the case of jams I mostly just want to make a bunch of music for folks instead of making my own games, so generally there’s no exchange of money involved, if that’s what you’re asking. 

I am open! The easiest way to communicate would be to DM me via the jam Discord.
