Yeah, no.
The first time, I got a hit, and the game locked up, not allowing me to make any more shots.
The second time, I managed to cover the entire opponent's board so no space larger than two squares was untouched, without a single indication of a hit, before my fleet was destroyed. Upon my "loss," the opponent's ships were revealed... every single one of them hit in at least one square.
Overall verdict... good idea. Really bad execution.
