In the last three games of Leviathan Harpooning I've played, the game is taking away turns. For example: I'm playing level 6, which starts with 36 guesses. When I got to 27 guesses left, the next click took me down to 20 guesses. When I got to 16 guesses left, the next click took me to 7 guesses. When I got to 4 guesses left, the next click ended my game. In the next game, I went from 20 guesses to 10 in one click. I'm using Chrome and Firefox 32.0.2 on Windows 7.
That's really strange. Is this still happening? Have you tried clearing your cache?
