Yeah, in the hectic rush at the end, we forgot to add any sort of win screen. I do actually really like the idea of being able to freely converse with people after you get your coffee.
You are supposed to be able to bypass the troll. There are a couple paths through the town, but rushed map design at the end led to it being unclear that the alternate routes were intended (though, the out-of-bounds routes were... less intended).
Also, I had a lot of fun watching your video. Always exciting to see someone react to a thing I worked on! Going to watch the rest after finishing this reply :) What you got from the salesman, by the way, was... an invisible treasure chest! I may have introduced a bug in the last few hours that made every interactable element (including the chest and the coffee shop door) invisible after you talk to the salesman. Woops!
