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. No in-app purchases required. • Contains horror elements. Player discretion is advised. • Video uploads, livestreams, and Let's Play content are welcome. • Reviews, feedback, and comments are greatly appreciated. 【Video Content Guidelines】 • Individuals and companies may create videos or livestreams featuring this game without prior permission. • Monetization is allowed only through the monetization features provided by video-sharing platforms. • If possible, please include the game's title in your video title and a link to the store page in the description.

Create a Micro, evolve it in your lab, and spread its colonies as you walk. MicroField is a location-based game with a Japanese gameplay interface. Terms, privacy information and the age gate are available in English. MAKE YOUR MICRO Choose a name, shape, color and starting traits for a fictional digital organism. Its seeded cyber appearance and generated name modifier give your creation its own identity. WALK AND ESTABLISH COLONIES Visit nearby places and check in. Recorded walks earn game credits and materials, and can leave Micros along your route. Watch colonies spread as colored particles across the map. CHOOSE HOW IT EVOLVES Spend DNA and materials to improve spread, persistence and other traits. Compare changes in the lab before evolving. Select one shared trait: transmission, persistence or symbiosis. Each changes how your Micro spreads, how long it is carried or how much it affects its carrier. STUDY WHAT YOU ENCOUNTER In-game infections leave samples you can analyze by walking. Use care to recover and gain immunity, or carry a Micro to another place for a delivery reward. Samples remain available for research after recovery. PLAY SOLO, OR JOIN THE SHARED FIELD Environmental Micros and research tasks let you progress without nearby players. If you choose to join the shared field, Micros can travel between people who visit the same places at different times. Both players do not need to have the app open together. Relay totals appear in your records. START WITHOUT AN ACCOUNT Real-world play requires location permission. A separate demo lets you try a fictional city without it. Optional motion access can turn available device walking history into game resources when you next open the game. Always-on location permission is not required. For ages 13 and up; minors need permission from a parent or guardian. Players aged 18 or over may opt in to banner ads in Records after privacy checks. Ads are off by default and can be turned off in settings. There are no full-screen ad interruptions or rewards for watching ads. Infections, immunity, medicines, facilities and resources are fictional game mechanics. They do not describe real health, medical treatment or infection conditions. Stop somewhere safe before using the screen. Map display and sharing require an internet connection. Districts and facilities are fictional game markers; interact from a publicly accessible location within 180 meters. Initial version: guest play only, with progress stored on this device. Apple account linking, cloud saves and cross-device recovery are not available.

Verdict
The clearest difference is ads: AnomalyAquarium at none against MicroField's shown. AnomalyAquarium also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, update cadence and in-app purchases there is nothing between them.
