I wish we had. For unknown reasons, he didn't post a download link. He said he would create a WIP thread, but he didn't.
I´m very interested in these changes too. After the first playthrough the game gets quite easy. A hardcore mode sounds awesome. After looking into the files i must admit that it´s quite a lot of work to change all item prices. I hope you can manage to release a mod. Sounds like you put quite some effort into it - i hope you keep up your good work.
Here's two mods someone just made that make the Community Center bundles harder. http://community.playstarbound.com/threads/bundles-completion-requirements.114281/
Actually we do. This guy created a mod that change the base prices. If you guys want the game to be harder go check it out. http://www.nexusmods.com/stardewvalley/mods/352/? Its been mostly hidden from the public lol. Almost all items game got re-balanced(according to him anyway.
He made the thread after I posted here. 1 day after, april 25. I did searched the forums before I posted, only a fool would complain without searching for the thread first. But don't think I don't appreciate your posts. Thanks for the links, guys.
