My colleague Fredrik wrote about this game earlier after playing without a guide. After reading other people's reviews, it was easy to agree that it's a bad game. But we found out that many gamers (especially from the US) don't have enough patience with games like these.
The game is about a famous japanese pop star duo and you control both of them at once. There is no GameFAQ for this game but we found another page with useful information. The game is definitely more fun and playable once you figure out how to play.
* Instead of going right towards the wall on the first stage, you can go up the stairs to the left, making it possible to proceed to the next level (pressing up+right+left+fire button).
* You can walk up to an enemy after you stun them and press up. It gives you items that increase your hearts (time) and a cassette tape needed to enter the studio.
So the game isn't as impossible as we thought. You just have to know about these two things. But it's still a really weird game. You can buy it from us here when it is in stock.
