Note: It took some time for me to get back around to finishing comments on the jam games. Pardon the late comment!
I had a lot of fun with this game! The concept of a Christmas trading adventure is fun, and it's integrated really well with the funny writing. The personality of it is excellent to read (and has some good self-awareness on top).
I did find that the music suffers from a lack of looping, which makes the game audio awkward at times - but it is nice to listen to and helps set the stage when combined with the writing and visuals.
Overall, it's a very enjoyable Touhou adventure, and easily a favorite. Well done on this jam game!
