Meh. I can't help but compare this with Marvin.
You know, Marvin Spectrum? Almost exactly like this game except instead of a spinny screen you have to change colors? Yeah.
I felt that this was too heavily influenced by Marvin Spectrum, almost seems to be a direct rip-off. Also, sad to say, but Marvin pulled it off better. Marvin's color-changing gimmick was better than the spinning gimmick, and I loved MS's music too.
Would be much better if it wasn't so annoying, (I don't like your gimmick) a bit more colorful, and didn't seem to be a direct rip-off.
