Aeternum Grand Plaza is an anomaly-seeking game set in a hotel with different scenarios and inspired by "The Exit 8". In this game, the player must progress through the various floors of the hotel, trying to reach the exit while observing the details of the hallways they walk through, looking for strange elements that might indicate it’s not the correct hallway. The procedure is simple: if the hallway contains no anomalies, the player must continue forward to advance through the floors. But if the hallway contains strange elements, you must turn back and keep ascending floors to try to reach the exit.
