Exit 8

Based on the global hit eponymous video game created by KOTAKE CREATE. A man trapped in an endless sterile subway passageway sets out to find Exit 8. The rules of his quest are simple: do not overlook anything out of the ordinary. If you discover an anomaly, turn back immediately. If you don’t, carry on. Then leave from Exit 8. But even a single oversight will send him back to the beginning. Will he ever reach his goal and escape this infinite corridor?
