A great game!
I am very rhythmically inclined, but I had a hard time with this game. Since the voices were not synced to the beat, I hat to click slightly after the beat, making streaks impossible. Because this game was greatly executed in every other way, I'm going to assume that my browser or flash is at fault for this error. [:
I must say, I loved the art, and the game is very well produced. It is also very original and addicting. I will most likely purchase the actual game. (Assuming that there no sync problems exist in the actual game, it will only be 10x better.)
I know that this is more of a demo, but I would like to see it developed more. More commands. Maybe having it change a little would keep it interesting. Also, having off beat notes would make it a little more interesting as well. i.e. eighth notes, half notes, etc. But, maybe these are features of the full version.
This game deserves higher than what it has. If the the syncing was improved for those of us having problems, I am sure this rating will improve.
5/5 -- A very well executed and original rhythm game full of great art.
