I once pressed continue without a save data. Weird thing happened, I had -26 HP and - 56 with ever rising flux. Also, no stairs, or monsters, just a big cavernous room. But I was level 1! interesting game overall, just need to get the hang of that spell system.
I would like more control over the avatars, I mean, instead of giving you two options, when it's fully upgraded, EVERY avatar should be unlocked. Food for thought.
secrets: Crew and Sails affect AP, while hull effects health, so aiming after the crew and sails (depending on your opponents ship) will reduce their AP, while going after hull does more damage. Also, Flying Dutchman? Way OP, took me three tries with full upgrades including bonuses on the best battle ship in the game. (Including Dynamite)
