I've played a few hours of the game so far. The walrus AI is absolutely horrible. I don't understand how you could possibly release the game with the pathfinding the way it is. My walruses have frequently gotten stuck on things (low walls mainly), or just been completely incapable of navigating around a large boulder. Assuming they even arrive at their destination, they often spend 80% of their time badly trying to navigate around something (like a low incline).
I feel like I'm spending 90% of my time babysitting walruses instead of playing the game. I find it appalling that you were willing to release a game with pathfinding this bad. I want to play the game right now, except I'm not, because I know I'm going to have to deal with the terrible pathfinding instead of actually playing it.
