Cool!
I think this game could be a lot better but it is pretty good as it is. A lot of people (like me) may be confused at the start and (unlike me) quit right away. After I figured out what was going on and got the hang of it, I couldn't stop. Awesome, but just some basic things could improve it immensely. First: A tutorial level. Second: Looping music, preferably more than just one song. Third: Difficulty settings or alternate modes. (ex. Survival mode, infinite enemies, gets progressively faster and slowly adds in more colors.)
