Look no further.
Nice! I also often use https://thenounproject.com/, they are not game specific but they have some very nice sets in very peculiar styles.
For my portfolio for instance, I ended up getting some icons from this set. The guy went all the way and remade 200+ icons in that style!
Nice one @ciro . it looks like they have free AND paid options?
Yes, they allow to download most icons for free, provided you put some credits. Otherwise you can just buy them and use them with no limits.
