Thirty Days

Thirty Days is a one-screen survival strategy game. You are keeping one thing alive for thirty days. Every third day a raid hits. Each day you gain one edge, then choose: BANK it to grow your keep toward a cap of five, or RUN to gamble one edge for a fifty-fifty shot at two back. Raids are announced at the start of the day, and the buttons show the exact hit you will take and the edge it costs to block, so every loss is your call, not a surprise. The difficulty ramps: the first raid caps at strength one, the second at two, after that it can roll three. Carrying a big pile draws more fire. Reach day thirty with anything left and you win. Under perfect play the ceiling is about eighty-nine percent. It is fast, deterministic per seed, and made to be replayed.
