User blog comment:Dentface/Phase Files Sneak Peek: Medium Ship of the Line, PvP Island, and More!/@comment-1051147-20130506191655

I actually have copies of the Tower images but not from the Phase Files, rather from the digital artist who designed them. He posted them as part of his gaming resume.

As for the concept, its very fitting.

In fact, in the Pirates of the Caribbean: Master of the Seas they've recently added fortresses as well. Your ship circles the island while you blast away at it.

It floors me the sparks of creativity that tiny game has had recently and nothing they're doing is out of the scope of POTCO
