Rusty Dagger - Den of Rats (complete) (spoilers)

About Rusty Dagger, from BoardGameGeek:

Rusty Dagger: Solo Adventure Zine Game is a set of print and play rules that require very few additional items to start playing. All the features of the big box games have been packed in: hero creation, companions, Item list, leveling up, Enemy AI, and skirmish combat. Time for an Adventure! You play a hero and follow an adventure booklet. In this booklet you will alternate between narrative challenges (convincing a companion to follow you, avoiding a trap,...) and combat challenges. The combat challenges are played on a tile that you can print or build yourself. In these challenges you have to eliminate the enemies. You must defeat the end boss to complete the adventure and gain experience. With this experience you can upgrade your character and participate in more difficult adventures.
