Offline support?

Hey!

This is very fun, but could it be made to work offline for cases where the user running may have restricted internet?

It shouldn't be too hard, I think the roll.sh just needs to be edited to remove the downloading of the audio files.

or maybe it could download it once and store the data on a cache folder somewhere
