I recently played a Japanese Fishing Game that now retails for about $200. This was better. It really exceeded my expectations, and I'm excited to play more of it. Such a satisfying experience!
Thanks!
That damn Ahab got me on the first run, but managed to pull out a victory like 10 seconds before the end of second try. Very suspenseful and satisfying. Great work with the game!
Nice! I was worried it’s too easy, glad to hear not everyone beats it on the first attempt.
