the only thing i would like to change you unlock things by saving up score not by high score
In terms of pacing, this is a pretty standard avoid game. I'm glad I found one of its kind that doesn't involve hentai of any kind. Now, the fault of this game is that the design is a bit too simplistic. It was still pretty fun to play, it could have just been detailed better. What's also cool is how these little powerups just keep whirling around the screen. Their appearances are so random, they're probably not even worth seeking out.
You're better off just letting them hit you as that certainly happens. The music was good and it's great that you have such a wide variety of music. I think my favorite powerup is when the colors get all flashy. It doesn't amount to that much, but it's still nice to look at. The text could have also been presented a bit better.
Don't play too long or you will end up throwing up an array of color.
