HDKATTUI - A Terraria Interface Pack by Techdude594 and Kiddles
That's exactly what I was about to post, but yeah. I'd like to second this. I just got Terraria gifted to me by a friend so I decided to check out what mods there are for it. And every time I find one, it's either a dead Mediafire or Dropbox link, like this one.
Do people just not care about this anymore, or what?
