What a well balanced game! Each playthrough taught me something new, the monsternomicon was indeed all I needed, and after winning a few different ways, finally seeing the dragon all alone was so rewarding. Very well done! This is my new end-of-day unwinding game.
EDIT: as I am starting my next playthrough, I'm finding myself wishing for a game clock so I can see how quickly I can get through it. I get why this should not be rushed by default, but a race mode to do best times for a given final score would be great for "late game"
