虹夏的呆毛

虹夏的呆毛 is an unofficial fan mini game inspired by Bocchi the Rock!, featuring Nijika and her ahoge. Players rapidly tap to make the ahoge grow upward, aiming to break through atmospheric layers, planetary orbit and even light-year deep space while unlocking unusual encounters along the way. The game emphasizes hand speed, endurance and combo responsiveness, with an iOS-native port optimized for touch sampling and quick follow-up input. It runs completely offline, making it convenient for short play sessions whenever inspiration strikes. The project has received authorization from the original creators and the port developer and is open source on GitHub. Interested users are welcome to download and install it from iOSIPA Software Network.
