I really enjoyed the old Italian townscape, the style in which the story is told in fragments on posters, and the action elements that make use of pizza as much as possible!
The map structure is quite high and low, and I could tell it was carefully crafted.
I especially like the place where you can see the back of the stage quite far from the top of a long bridge.
Also, the song in the credits was a lot of fun to listen to, meow~!
