In Treasure Island you explore a mysterious island in search of a legendary treasure while dodging deadly pirates like Long John Silver. Played in real time with static graphics and a limited parser, the game introduces unique features: every action drains energy, so eating is essential. A telescope helps you scout, time passes with a day-night cycle, and flags let you mark your path. You can sleep to skip time and save the game at any moment – if you survive long enough to need it.
