Update v0.7.7 - Study / Work Mode added + More
This new update brings both relaxing features and new challenges to your desktop aquarium:Study/Work Mode: A peaceful mode where your fish don't need feeding or cleaning. Perfect for when you're busy or just want a stress-free background.Fish Hook Mechanic: A new threat to your aquarium. If you're not quick to react, the hook will steal one of your fish. 6 New Fish Types: Expand your collection with six new species.New Color Preset: Add a splash of color to every fish with a vibrant new palette.Leveling System Rebalanced: Leveling up is now slower, offering a more satisfying progression curve.Feeding Adjustments: Fish take longer to become dark when unfed, so you don't have to feed them as often.Bug Fixes: All known bugs have been fixed to improve performance and stability.I plan to keep expanding Desktank with tons of new features while preserving and improving the relaxing experience it already offers. I'm working on adding more idle mechanics to make it feel more like a full game, but I also want to keep modes where it can simply be a peaceful companion without any pressure. Customization is a big focus going forward—I'm aiming to give players more ways to personalize their fish and their desktop. In the next couple of updates, I’m planning to add fish storage, a store for unlockable visual upgrades, and of course, more fish species with every update. I'm also always open to suggestions, so feel free to share your ideas!Thanks for playing and stay tuned for more updates soon.Read full article on Community Announcements (edco)
