glad you liked it, yeh edges of the map are a bit questionable however theoretically you should never fall off as the boats are y locked, but the crew aren't...
didn't really know what to do with it as the navmesh agents don't work well with regular colliders so i couldn't put a wall... I did think of having a force which steared you back towards the center (with a wave graphic) howevefr this was too complex for the time limit
