I have some ideas in my mind so let me show you it!
Metal Flooring-Much better than the simple one but quite pricy!
Large General Storage-Bigger The Better Right?
Coal-Can be collected by mining coal ore[Dont get angry on this one mkay]
Coal Ore-Can be found on Metal Deposits.
Metal Bucket-Much Better than the wood version!
That's All![I Might Add Some MOAR stuff so yeah thanks!]
