Suggestion: Actually tell users when their den is full.
Other suggestion: Let users purchase den space instead of telling them that their den is full and the wild wolf couldn't join.
I just spent a completely unreasonable amount of time WW hunting and then got a den full message and I am going to throw my phone out the window.
That little teeny 10 wolves / 10 spaces notice ALL THE WAY AT THE BOTTOM OF THE PAGE? That you have to scroll down ten miles to see?
It is not adequate. Especially on mobile.
The site warns you in giant red text if you need a pickaxe. I don't care about pickaxes. I am here for the RNG wolves and I just missed out on one because the site didn't tell me I needed to spend some of my 20 million pebbles on den space.
I didn't even get a knucklebone.
