The game so far is a lot of fun. Worm's introductory dialogue had me in stitches and the battle music (though a bit repetitive after awhile) is pretty good. That each character's dialogue gives them a sense of personality is so often missing from these games.
I had a few suggestions;
Vary the battle music a bit, maybe use a few tracks to keep them fresh. I read above you're trying to get some metal tracks and that would be great.
While I like Aya, I'd rather the healer be a goblin to keep up the idea that the gobbos are the main characters here. Maybe a shaman? No pink skins in my war party!
The last one's just a hope we'll get a resurrected certain someone eventually. I like her attitude and want Grolokk to knock her down a peg.
Keep up the good work.
