A turn-based puzzle roguelike. A lone kunoichi ascends an endless castle — read each floor, arm yourself from its walls, cut down the oni. One wrong move ends your run. Read the board. Take your turn. Survive. An endless castle rises before you. Each floor is a locked room — a puzzle written in steel and blood. You are a lone kunoichi, and the only way out is up. KAREI is a grid-based, turn-based puzzle roguelike. Every floor is a self-contained tactical puzzle: enemies move when you move, and a single careless step can end everything. No button-mashing — only cold calculation and nerve. ■ A castle that never ends No two ascents are the same. Rooms, enemies, and the treasures hidden in the walls shift with every run. Climb higher, and the castle pushes back harder. ■ The walls are watching Faintly glowing walls promise items. Ominous walls conceal weapons, cursed charms, and things best left buried. Learn to read the castle, and it arms you. Misread it, and it buries you. ■ Cut down what stands in your way Demons in the shape of oni guard the path upward. Each demands a different answer — a different line of movement, a different blade. Master your tools, or be mastered. ■ Easy to learn, brutal to master Move, strike, ascend. The rules are simple. Surviving is not. —————— This release contains the first ten floors of the endless castle. It is complete and playable on its own.
