After my first few play-throughs of Stardew Valley, I felt it was too easy to get rich, and the monsters became very easy once you get used to the combat.  When a game is too easy, I always turn up the difficulty setting.  So that's where this mod comes in!

How it works:
-Monster Damage increased by 200%
-Monster Health increased by 50% (except ghosts)
-Item Values decreased by 50% (except seeds and crops)
-Crop profits decreased by 50%
-Increased crafting recipe materials by 100%

This mod's objective is to make the game more difficult without losing the general great feeling of Stardew Valley's gameplay.  It is designed to make combat more challenging without being annoying, and to make all money-making strategies more difficult without feeling too tedious or punishing.  It still plays just like vanilla, but harder!

I found that after the difficulty increase, every minute of every day feels more important and the game remains challenging for far longer.  I was also happily surprised with how a number of things in the game are now much more rewarding, such as delivery quests in town and gifts received from townspeople after making them like you.

Please leave a post with any interesting gameplay experiences due to this mod.
