Hooooly! I love this idea, it is soooo great.
So let's start with art. It's great. The art style is simple, looks nice and really fits the gameplay. It gives me all of the necessary details (where are wolves, where are deer, landscape) while also being clear enough for me to make plans. Great!
Gameplay is suuuper cool. I love the idea. I agree that it's a bit hard. I found that I was missclicking a lot when executing an attack which made me feel like the wolves are super stupid. Would be nice if when a deer is running straight at a wolf, the wolf would actually try and attack without my input. Other than that it's sooooo coool.
Unfortunately I don't see the theme. Even if we take "Take a deep breath" as "Take a pause", pausing is not a big part of the game.
Anyway, I would love to see this game be developed further. Would probably even buy it.
