Update:
Does not work anymore and seemingly unmaintained. Lowering review. Time to open source?
Original review:
A couple of issues.
The developer site lacks an easy-to-find feedback area, so I'm leaving my bug list here.
This is an impressive logic puzzle with the caveat that it can generate non-unique solutions to puzzles. Specifically, I've run into several boards where a single-masted ship can be legally in either of two positions. (This happened on level 2, which doesn't bode well for higher levels.)
It isn't always clear when the game is over.
Fix the ui controls relating to game completed successfully, clearing the board of ships to start over with the current guesses, etc.
Without these bugs, I'd give the game 4 stars. My experience on the store is that lower ratings provide incentive to fix bugs.
