Anomaly-Finding Game Inspired by Exit 8 – Now on Mobile! The 6th entry in the popular anomaly-spotting series is here! This time, the setting is an aquarium. 【Story】 This is a popular aquarium in town. You have just started your first shift as a night security guard. As you enter the aquarium looking for the other staff members, you find it strangely deserted. Then you discover a manual left behind on a desk. It reads: "If nothing seems unusual, leave through the exit on the right. If you find an anomaly, return to the exit on the left. Each correct decision will light one lamp. When all 9 lamps are lit, your shift is complete." And so begins a night filled with far too many anomalies... 【Features】 • Simple and easy controls designed for mobile devices. Move left or right and tap the screen to zoom in and inspect details. (Perfect even for players who are not comfortable with complex 3D controls!) • Discover over 40 different anomalies. Some are subtle and difficult to spot, some contain horror elements, and others may make you laugh. Since anomalies appear randomly, every playthrough is different. • Automatic saving after each round lets you enjoy short play sessions and quit anytime. • Fully playable offline, making it perfect for commuting, traveling, or passing the time. • A game that tests your observation skills and memory while giving your brain a fun workout. 【Important Notes】 • The game may not function properly on older devices or operating systems. • Completely free to play.
