"A card rhythm game themed around shanties" is a work in progress, and probably will not be radically finished before the end of the jam.
The biggest weakness is graphics (no practitioner on the "team"), the card example below is with the nicest icons... And also, there is a problem with a title, suggestions welcome! (not necessarily after reading the rules to see what it's about, but maybe?...)
Ruleset pdf is here:
