Could you make the small print smaller as it takes up half of the post
And I not really sure on flint ore since you can already get it from gravel.
Any way it looks good as long as you coded it yourself.
I added flint ore because I disabled stone tools I didn't want it to be really hard to go from wood to flint since that would be really boring if you had to sit there and break gravel until you got the flint you needed.
I did use base minecraft code for the ore though.
