Thriller

Minesweeper, in first person. Step onto the board deep in dark, ancient ruins, read the glowing numbers, and dig with your pickaxe. Just don't hit the wrong block.

You've started a short-term job at a swan boat dock on the Han River. Sell tickets, tie up boats, cook ramen at the convenience store. Ordinary days. But there's a missing-person flyer on every lamppost, and the man who put them up sits on the bench outside the dock every day.
