Just popped in to say you have one nice game here. Hope you are doing well and continue to expand on the excellent thing you have going here.
I am studying JAVA on my own and using your program as examples and trying to figure out how everything works. Maybe in a couple of months I can start being almost productive.
Also if you need more graphics for monsters and such I could help. I like working with the bit images.
Take it easy and good hunting
if the image fits with the other images, we are always ready to accept your creations.
