The Dink Network

I have killed the 2 guards in the second town but now I can't get past the rock in the road. The tax collector tells me to go away and the only other charachter in the game doesn't say anything. Have tried everything I can think of, do I have a bug, or am I just extra stupid today? hints?

Another tricky one. You have to find a cave, which, though visible, is partially obscurred from view.

dude, i found the cave easily but what i have to do from there is unclear. i'm basically in the same boat whether i found the cave or not...help!

i'm stuck after you kill the bonca underground and warp somewhere. theres a castle u cant get into and some dude that wishes he had a bonca skin, but theres no boncas around? any help?
