This, I must say, was a pretty nice start ! I'm a bit ashamed we can't use the time to visit the town to check on what happened on coffee gal. There is a bit too much thread left open so I'm waiting for the continuation of the story!
However, I have to say that I was less appealed by the combat. The idea itself is pretty fun, but the implementation was not my cup of tea: at the end of the day I just felt like clearing or not a combat round was entierly at RNG's mercy, which is not exactly fun to play.
One last nitpick: what happened to all of that water in the basement? (fair warning: it's pretty late here, so I may have dumbly missed the explanation, apologize if it is the case)
