From the introduction:
Brasst Issinn is an intense, short form scenario about disappointed love, fermented resentment and ice cold air. The scenario switches between storytelling scenes about the boy on the thinner and thinner ice, and scenes in the cabin, in which the players develop the quiet buildup to the inevitable row. The game ends when the row breaks out - and ice breaks under the boy.
The game progress is tracked with tokens and a status board, both included as print-and-play components in the document. The tracking board can also be downloaded as a separate one-page PDF document.
