I played this last night and had a lot of fun. Some really great atmospheric and aesthetic choices in this game, which helped us all get 'immersed' in the story. The story itself was also really interesting and entertaining. I like that it had a very logical narrative that was accessible to us as players. I often find a lot of adventures, both official and third party, are too all over the place with the narrative and that you end up getting lost.
Highly recommend this adventure to anyone interested in Mausritter. It's a wonderful introduction to the system and has some really fun magic items, too!
