Knight Mansion - Hard

[Spiak]

I finally beat Knight Mansion Hard. But I got 108% secrets. Is that normal?

Another thing for Vern to fix and another feature to Midnight Mansion v1.0.8!  ;D

I finished this mansion with 78% secrets but I've reached the exit with a spare blue key. After searching the map and making sure there were no blue doors left closed anywhere in the mansion there are two possibilities: is there a secret where you need a blue key and I didn't find it or is it one extra key in the mansion? Thanx for help
