Pop the bubbles.. not a rhythm game.
Graphics - They were fine, although they must have been ripped from WMP or something. -.-
Style - Boring concept. Oh, and it's not a rhythm game. Add some arrows etc..
Sound - Strange music ranging from drums to orchestras in the same song, usually ending in some horrible screech. I think rock music would be good..
Violence - N/A
Interactivity - All the buttons work I guess.. Controls were sort of difficult to use seeing as there were thousands of dots around. Like I said use some sort of arrow / button system.
Humor - N/A
Other - Can you please compress your files? I don't want to spend 15 minutes waiting for it to load. And if you have compressed them then cut bits out.. I don't know what you were using all the memory for.
Overall - Doesn't really strike me as a rhythm game. Simple gameplay with not much special about it.
