Nice idea, I really like the vibe. Big shoutout as well for the setup (“just flip it and play on”), that’s genuinely fun.
So the ship can’t turn back, right? Does that mean it can only move forward until it eventually leaves the map? In that case, the +1 movement bonus feels a bit useless, especially on maps with only three river clearings.
I also don’t think making the ship a token is the best choice, since it doesn’t really behave like a token mechanically. Maybe a pawn would make things clearer?
And maybe I’m just tired, but I can’t figure out from the board how they actually get warriors onto the map (do they move them from the quarters?)... and… how they score victory points!
