CyberAgent's rhythm game BanG Dream! Girls Band Party! has secured over four million downloads in its first six months of release in Japan.

The game is now being pushed out to Hong Kong, Macau, and Taiwan in a traditional Chinese edition. A new collection of cover songs have been released in-game to celebrate the game's launch.

Developed by Craft Egg and based on a Bushimo property, BanG Dream! Girls Band Party! is part rhythm game, part visual novel. Players form a band of anime women and perform songs on stage with simple tap-based controls.

It has proven a success in its home country of Japan, and is a consistent entry in the top 50 grossing ranks on both iOS and Android. It is on track to reach a similar level of success in its new territories, having already cracked the top 100 grossing ranks on Android in Macau and Taiwan.

CyberAgent considers the game a hit, though it hasn't explicitly mentioned this in its latest financials. That said, the company is currently seeing profits fall across the board despite revenues continuing to grow.
