Hmmm.
Now that I've played a little bit, having no sounds can be a little annoying. Having no sounds also translates into having no pauses in the gameplay when a sound would have normally been played (e.g. if a monster dies it just suddenly disappears).
So I'd like to know how to fix this, but if not, that's fine; at least it's playable now.
EDIT: Oh n/m, it turned out, after a little online searching, was I had a sound card driver problem. Thanks anyway.
