Nixel Google Famicompo mini Vol 9. I think song 27 is the one you're looking for if it's the Map music you're talking about :) It's all actual NES chip music, not mp3s, etc. You'll need NSFPlay or a similar tool to listen to them.
After listening to that song a few times, I've grown rather fond of it. I think I may end up using it for the final stage where the dwarf has to escape hell with the giant sword.
As far as the dwarf goes, he's almost entirely finished. He has AI that is not player dependent aside of his follow distance. If an enemy gets into your "personal bubble" he will run to your side and start attacking. His axe strike (not thrown) is the most powerful attack in the game. Except for when the hero goes berserk/is possessed in stage 13/14 and the second last stage.
linkaevolution Thank you for the kind words! I'm glad you like it!
The addition of the dwarf makes the game way too easy I find. As of stage two he's your constant companion as it happens in my comic. So I'm not sure if I should keep him there always or have a pick up that keeps him with you until end of stage...
