About this game

Prismkeep is a light-routing defense puzzle where you set stained-glass prisms inside a castle keep to bend torchlight onto every amber ember. Each wave you must nurture all the embers before the encroaching wall overruns the battlements, playing for score across mounting waves. A breach ends the run.
