Fluid Fortress

Fluid Fortress is a modular, high-fidelity Flutter application engineered to run a physics-based hydrodynamic stream routing and pressure resonance simulation. The codebase is strictly organized across specialized directories: lib/aquifer_chassis for local persistence registry and fast-fade routing, lib/hydro_panoramas for welcome onboarding and custom-painted main terminal hub panels, lib/fluidic_lock_matrix for the multi-phase game engine loop and upgrade refinery studio, and lib/reservoir_registers for charts, statistics, and milestone ledgers. State persistence is managed through SharedPreferences configurations saving highest scores, active level stages, upgrades, and achievement nodes.

The core gameplay implements a strict five-phase state machine simulating mathematical fluid routing paths, hazards dodging, and wavelength polarity matching. The custom rendering system uses Flutter Canvas API pathing, linear gradients, and radial shaders to render fluid streams, rotating valves, perimeter locks, and sloshing reservoir waves. An analytics dashboard compiles decoding accuracy ratings, multiplier peaks, and stabilization risk ratios, while the achievements cabinet draws unlocked milestones as interlocking polygonal glass shards. This software functions strictly as a skill-based technical mechanics game, utilizing authentic physics and hydrodynamic terminology.
