fun, challenging and addictive but needs tweaks

I enjoy this game, great for quick gaming sessions. as others have mentioned, it can be frustrating as you get further in a session and run into an impossible task based on the colors available. but my biggest complaint is that the game overrides all other sounds, meaning I cant listen to iTunes while playing. this is a simple but crucial user experience tweak that would add at least 1-2 stars to my review.
