Polderfall

A cooperative strategy game about keeping a low-lying region dry through one long, worsening storm season.

Polderfall takes place in six fictional regions inspired by real Dutch landscapes — peat meadows, river forelands, reclaimed sea clay. Each region starts the season dry. Each night, the water tries again.

You do not fight anyone. You plan dikes and drainage, build and repair pump stations, schedule crews, and choose what to protect when there is not enough sand for everything. Lose a field and the water spreads into the next. Lose a village and the season gets a lot longer.
