Almost level 20 now.

You can upgrade your van similar to how your house on the normal animal crossing games works, expanding it and then having to pay it off over time.
When you have 5+ friends on the game you can start to play a mining activity for some extra rewards.

I seem to be getting to the point where I have to specifically pick which kind of animals I want at my campsite due to having to upgrade your tents which will only increase the max levels for specific types.
So now I have to start picking out animals based on those types(cute, cool, nature or sporty)

Kinda sucks but I guess down the line you'll have all animals unlocked and everything maxed out so it doesn't matter too much anyways
