Thanks for the detailed feedback!
Those are some good ideas that I probably will steal!
I do wish I had the time to put in sound and I think in future jams I will try to do this much earlier in the process rather than save it for last, I think you are correct in that it makes a whole game feel better.
As good as it would be to have sound, I think you probably took the right approach by focusing on the gameplay first. A little "boop" when hitting the buttons and a "thunk" when putting items in the boxes (plus a music track in the background) would go a long way without taking ages to implement, but if you're seriously pressed for time then it's better to have a silent game that works well than one that has sound but never quite came together.
