A pollen avoidance game that uses physical calculations to prevent pollen from entering the nose. -โ€” Rules -โ€” - The game is over when a certain amount of pollen enters the nose. - Move the cursor to push the pollen out of the screen to score points. - Successfully pushing pollen out of the screen in succession results in a combo, adding to the score. - Squirting nasal fluid can protect the nose from approaching pollen. -โ€” Features -โ€” - A fresh and pleasant interaction experience with pollen. With simple operability and the adoption of realistic physics calculations, you can experience an unprecedented sensation of blowing away a swarm of pollen with the wind. - The pleasure of combos As the game progresses, it becomes easier to create combos. The larger the combo, the bigger the effect. - Flat design-based graphic expression The adoption of flat design has achieved easy-to-understand graphics. The amount of pollen exposure can be understood by the state of the character on the left side of the screen. -โ€” SNS -โ€” X: https://twitter.com/Tomii172848332 instagram: https://www.instagram.com/chiiiikt/

Create your own aquascape and watch it grow. Arrange aquatic plants, rocks, and driftwood, then welcome fish and shrimp into your aquarium. Feed your inhabitants, change the water, remove algae, and trim plants one at a time. Your care earns points as your collection grows. Discover more than 100 aquatic plant varieties, collect inhabitants, and track your progress with the collection and plant growth chart. Keep extra plants and inhabitants at the farm, and enjoy the changing scenery around the pond. Explore your aquarium in full screen with a sense of depth. Adjust your view and watch the light shimmer across the water and substrate. Your aquarium is saved on your device. Export and import JSON save files when you want to move a copy between compatible versions. Cloud synchronization is not included. Optional rewarded video ads are available when you choose to watch them. Real-product shopping links may include affiliate advertising; availability depends on the supported market. Discover 122 aquatic plant varieties, 269 fish species and varieties, and 77 shrimp color and pattern variations. Counts include selected varieties and color forms. Undiscovered species remain silhouettes until you acquire them. English common names or scientific names are used for your collection. Catch 26 insect species and color forms around the farm, watch eggs grow through larvae and pupae, and try insect sumo or safe practice battles. Explore the greenhouse and pond, store extra inhabitants, and follow their growth. The breeding and care rules are game simulations. Display your aquascape in home screen widgets, or select an adult for Dynamic Island on supported iPhones. Widget image updates are managed by iOS. Choose from nine interface languages in Settings: Japanese, English, Brazilian Portuguese, Spanish, Traditional Chinese, Korean, Hindi, Arabic, and Turkish. In non-Japanese interfaces, collection names use English common names or scientific names. Shopping-country selection uses the App Store region when available, with a device-region fallback and manual override. Affiliate shopping links are shown only for configured markets; overseas affiliate services are still being prepared. Discover 11 newt types, including rare Full Red and two Gold forms. Watch externally gilled larvae grow into pixel-art young and high-definition adults. Successful breeding between two adults of the same lineage produces two to four larvae. Healthy adults can be sold for in-game points. Watch newts float near the surface or in midwater, sink gently, and return to walking, resting, or swimming. Tap an angel left after a resident dies to dismiss it individually in care or full-screen view. Place accent plants on driftwood and branch tips; attached plants follow the material when it moves or rotates. Shrimp climb plants, rocks and wood, while young and adult newts climb rocks and wood. When the aquarium is full, new arrivals and newborns move automatically to available farm space or the pond, preserving residents, ages and genetics.
