We've just published a new patch for Hack 'n' Slash with a collection of bugfixes.

Linux fixes

• Linux configuration files, local save files, and mods now saved in a more appropriate location, following the standard used by other Double Fine games. You can now find these files on your local system in the following location:
  $HOME/.local/share/doublefine/hacknslash
  
• Subscribed mods now download and execute correctly.
  

Offline mode

The severe performance issues experienced when playing the game with Steam in offline mode should now be fixed. In addition, the subscription update process will now time out in five seconds if the game can't establish a connection. This should get you into the game much faster when playing offline.

Assorted other fixes

This patch also contains assorted fixes for minor bugs throughout the game.
