I think you guys totally have the feel down. Fantastic music. My only gripe is that while the platforming is often good, there certain areas where the design isn't all there. The Archivist area has some areas where to make the jump I have to bang my head against the ceiling, which throws off my jump trajectory. The punishment for missing a jump here is also quite high, as I fall back several rooms.
Overall through, I think you guys did a great job!
