Aw, thank you!! Well, I definitely know what "crunch time" feels like...and sometimes I have these grand visions for a project that have to get scaled down to a more manageable size with the understanding that maybe I can revisit the project later and do a better job. Case in point: I have a lot of piano recordings that need to be redone with better mics/piano/playing!!!
Ask away: I'm busy too, but what you have is that rare occasion when a musician actually does want to just "gain experience" with something! Most of the time, we hate being told "you'll gain valuable experience!" and then not getting paid for a gig. I'm still getting used to how game jams "work"/flow, but I imagine that it's okay to take music written for a jam and then rework/reuse it in some other non-jam project...so it's not going to waste even if the game isn't finished in time (or gets posted in an incomplete state).
