"How to get the steam overlay to work with the game"
1. Open your steam games menu/library and find the add non steam game option. Browse to your program files.. -> jre6 -> bin -> javaws.exe (open it up)
2. Ever get pacho's .jnlp file or the default jnlp from the site and put it straight in your C: directory. Rename it to hah.jnlp The game "javaws" will be added to your steam games list. Right click on the javaws game and select properties. Change its name to Haven and Hearth. Go to the target part. Leave it as is, but click at the end of the text box and add a space. Then put "C:\hah.jnlp".
3. Run the shortcut and the overlay works, so now you can pop that up in fullscreen or tell people when you're playing Haven and Hearth :D
It only works on the main menu D:::::::::::::::
EDIT: woah you can teleport to the village idol :D
