Cool, just nothing really visually interesting
The game is nice, and although it's not really addictive to me but I'm sure most people will play it for a while. All the things in the game work great and there's no real flaws that I notice.
Even so, there's almost nothing visually interesting to look at while you're doing this, it's just a long red line moving everywhere with green sqaures falling every 5 seconds. If you could add some thing to actually make the game look more interesting, like a background or some trippy effects, the game will possibly keep my interest for a longer time the end of the 2nd song.
