I owe all of my success to the panic induced by thinking the cooldown counter was the queen's death counter.
Thanks for sharing, that was a fun little hive! Apologies as well for the cooldown confusion - there a definite moments (like Old Bitey coming to visit) that I'd like to feel tense/stressful, but new Queen cooldown shouldn't be one of them! I'll have a think about the best way to reduce opportunities for confusion.
