Fishing Update for the CELESTAY Demo
Alongside “Idle Fishing,” where fish are caught over time, you can now enjoy a new way to fish by stopping the float at the right moment.In “Skill Fishing,” you use one fish to begin. Stop the float within the blue bar to catch a fish. Stopping it within the orange bar that occasionally appears increases your chance of catching a rarer fish. The deeper you fish, the more likely you are to find rare fish and treasures from a sunken civilization. However, the blue bar becomes shorter, and you must succeed more times to reel in your catch.Choose “Idle Fishing” when you want to focus on work, or “Skill Fishing” when you feel like playing. Enjoy your own slow life in CELESTAY, however you choose to spend your day.Read full article on Community Announcements (Takao Furukawa)Community & EventsOfficial
