I remain hopelessly stuck on level A12. The clue that has been given here has not been enough for me. Is there a video of the solution out there? By the way, as others have commented, this is a lovely game. The graphics are excellent and the game concept is quite interesting. While the drag controls are good, I find myself using the tilt controls to get a bit more precision when I need to fire the cannons. Usually I loath tilt controls on my iPad, but they seem to be fine with Manowar. Edit: I think making a post here was the key to solving A12, as soon after I got it on my own! The solution is much different from what I was trying to do earlier and is very clever. Also, amusingly, I found a Japanese language video where they struggled with A12 and were unable to solve it; they were taking my original failed approach.
