The Meaning of Life, the Universe, and Everything.
I just said this on a different thread and I will repeat it here. 1.5.2. is way too outdated for anybody to ever download and play it. I am pretty sure this is your first mod, and it doesnt look too terrible for it being so, looking at the fact you even brought in an ore that dropped not itself but an item (from what it looks like). Now, any progressed dev will probably just laugh at this, but a man's gotta start somewhere, right? I'm pretty sure their first work didnt look much different from this. But update this to 1.8. 1.5.2 is just way too ancient to get you any downloads.
