Recently I entered the high lvl arena and as a consequence the requirements to upgrade the event buildings jumped up. I always had the feeling that passing the low lvl boundary is a kind a of punishment to a dedicated player with respect to event requirements. In this event it might be true :-). I have more than 30 energy droppers and I am having a very hard time getting enough Oyster’s. Every time the wrong monster pops up while chopping. Draining my energy. After burning more than 700 energy I barely have enough Oyster’s to get the Prison to lvl 2. I guess this event is not for me. Unless I buy a few energy packs, but the main price does not contribute that much to my queendom. I most probably do something wrong, but it’s better for me to pull out the event (so sad) plug and focus on getting the fish. Artwork is as usual great! Loads of success for all of you in this event.
