Our take on Fishlets
Its defining structure is the split between a seven-level Adventure mode with invaders and unlocks, and virtual tanks where fish can be cared for, collected, customized, and observed in idle play.
What is Fishlets?
Fishlets combines aquarium care, collection, and two play modes.
In Adventure mode, players complete 7 levels, face invaders, and unlock fish, aquatic critters, and decorations. Virtual tanks provide a quieter setting for feeding fish, managing happiness, keeping tanks clean, collecting color variants, and watching fish swim and school. The game includes 48+ fish, 350+ color variants, rare unique variants, snails, shrimp, newts, axolotls, plants, and tank decorations. Tanks can be customized and upgraded. Fish also have swimming levels and individual behaviors. An idle mode allows tanks to continue running while fish move and interact, with hand-drawn pixel animation, ambient sound design, and a soundtrack.
