Customer Reviews


This game is great! Lots of songs to pick from and challenging gameplay. The only thing making me not give a 5 star review is the unforgiving reward system. If you don't score anything higher than a C, you fail the song. And, when you fail, it gives you no experience points. And then, when you do pass a song, the experience it gives you is very cheap. That wouldn't necessarily be a problem if you didn't need experience to get points, which you need to play songs. I mean, you can pay actual money to get more points, but that would be money down the drain if you play the game frequently(ex. 100 points= 20 or 33 songs depending on what level you play at).

Other than those mild annoyances, this is a great game and I highly recommend it to any one who wants a quality rhythm game.

Convenient Mobile Game

Nice to find this game in mobile. Brings back good memories =v=

Anyways, it delivers well for a mobile version. Good to play in four keys for a small smartphone but more keys for a tablet or so. They should have a place for players to see songs that they can play instead of going to the store everytime, or I'm missing something here. Someone I know said that they couldn't get free points from the advertisement because of some bug. Hope they could fix it.

In an unrelated topic, sadly I couldn't play the PC version anymore... It removed the game from my country. I even paid real money for the in-game content like songs and avatar wear. All went to waste.

Best Music and Challenge

The music is the best you can find in a game. The game has a lot of songs by K-Pop artists, but their originals have the greatest charm and feel out of all of the music.
It was actually challenging to play unlike North American games that rely heavily upon famous artists, and can serve up greater difficulty to people who can play on the really high levels.
