I rarely put any comments but with this one I feel that I have to! This is a marvelous game! The part that I liked most was the meeting of two alternative selve-ducks in a treasure cave. The idea for a block history is really interesting but with all those interconections (like writer/fisher) it became an outstanding piece of work! Keep it on!
