Decent.
The graphics were nice, I'll give it that. And yes, it had some good music. All in all, it was a decent game.
But:
-The difficulty was very low, and the hardest song was still pretty easy.
-The songs were really long
-It was annoying how the player moved back and forth, but then again, I guess you needed it to be a bit more challenging
-Every single part of the game was some sort of ad for the Azor.
And that's the part that most bugged me. I understand you can make money off of a good game, and advertising helps, but I don't see the need to plaster a logo over every single part of the game. It seems more like you made a game FOR the Azor company, rather than just having ads for it. When I would finish a song, I wouldn't get, "Here's what you did, oh, and here's an ad for Azor off in the lower right corner." It was more along the lines of, "Shave better with Azor, oh, and here's your score, which is less important in a game."
To put it simply, or in tl;dr, the amount of ads in this game is going to make me LESS likely to try one of those razors.
