This was my submission for the Fish Blade RPG Jam 

Fish Blade - Treacherous Waters is a semi-cooperative TTRPG about several fish who are sent on a mission of the utmost importance from the Queen of the Ocean. However not all is well under the sea; much more is going on beneath the surface in the Queen’s undersea court. Alliances may shift like the tides. Treachery and deceit lurk in the party as these fish form an uneasy alliance while pursuing their own agendas. Will your group be able to complete their mission?

I made a trailer for the Fish Blade Troubled Waters as well. I think it is pretty good
