A possible suggestion or feedback, I think it could be helpful if after you "fail" the night to maybe tell the player what the anomalies they missed were? Not sure if it would make the game too easy though.
Because when I get the alert there are "too many anomalies" and I can't see anything out of place resulting in me losing the round is a little frustrating, but it isn't horrible.
Like maybe just put a list of the rooms the anomalies we missed were in but don't say what they were.
