This is awesome. The colorful graphics are awesome. The music is awesome. Simply put, this is an awesome flash. This defiantly deserved the Daily 5th place it received, if not better. The easter egg is awesome as well, despite not receiving the medal for it.
I'm personally not colorblind, but it's really unfair that the colorblind can't play this game and receive the medals for it. Perhaps you could find some way to create a colorblind mode. Having a colorblind mode would make this game open to a wider audience, and it would be a cool little thing for non-colorblind people to play around with.
I think you should be able to customize the controls, or have it so it tells you what button to hit in every color. A lot of the time, due to how fast it started moving, it was very hard to process which key goes with what color.
