I don't know if you've noticed yet, but every achievement you complete will earn you Anka Tokens. These tokens can be used to buy items from the Token Shop. The items in the token shop are sometimes extremely limited, so it's good to save enough to buy whatever you'd like to get beforehand! Not that there's reason to worry, of course. New achievements are being added quite often, so you can always get more.
