Ah, that makes sense. I think I should give it another shot (so to speak). I'll have more time tomorrow. Also, you're probably right--there was a master slider, and I somehow got confused and expected music. But still, music would be cool!
Re: playtesters, I didn't have any, and it definitely would have helped me. It just didn't occur to me to try to find some because simply producing a game seemed like a lift in the time we had. So I applaud you for having anyone test out your game at all!
