About Mercury Barometer
Mercury Barometer is an offline weather forecasting simulation built with SpriteKit. You play as a village weather observer stationed at historic observation posts across the world, reading classical mercury instruments to predict the next day's weather and keep your village safe from storms.
Three instruments, five weather types, fifty contracts across five atmospheric observation stations. Read the pressure, temperature, and humidity, infer the incoming weather, and protect the village health bar.
