@Mishima - Neither. The fact that they made each mouse puzzle bigger than the last, without actually making the dungeon thematic gave me a sense that they gave an intern a shot at level design, ran out of time, and were stuck with it.
Every other dungeon has put together in a comprehensive way that makes it fluid and flows. This is literally a cluster of "Be a mouse, unlock door, run through vent, hit switch rinse, repeat".
