I liked the fog mechanic and tower defence overall
Didn't quite get what storm-protection buildings are supposed to do. Thought they will reduce fog around, but I guess they protect from occasional storms which spawn on map sometimes. Also, some mechanics are unclear. If I clear the fog/clouds with my cursor, will my towers attacked units which I spotted? Will my units attack unspotted enemy boats when they are hidden but in range? (i guess answer to 1 - yes, to 2-nd - no)
