You are stuck in a prison with endless blocks where notorious criminals are located. This is a prison famous for very horrific events. To go to block 15 and find the escape route in the prison, observe your surroundings carefully and take the envelope given by the guard at each block pass. These envelopes are important for your escape plan! Do not ignore any anomalies. If you find anomalies, turn back immediately. If you do not find anomalies, do not turn back. Move forward. When you reach block 15, 3 different doors are waiting for you. You will encounter different endings and puzzles in these doors. If you solve the puzzle at the end, your escape from prison will be easier. Good luck… Playing Time 20-90 minutes
