Love it, peed my pant without hesitation. The tone of the story is broadly fun and playful and it gives Lupin the characteristic everyone is expecting. There are more than enough fun little details throughout Lupin's escape, and I love them.
I got pretty short endings for the first two times, and I think balancing the amount of content between each different branches would be nice. I see choice based games as text mazes sometimes, and I feel like sometimes having dead ends reveal themselves much later in the story might frustrate players a little bit, but definitely keep them immersed and interactive, rather than having dead ends exposed right away.
Overall, so much fun reading through it!
