Beautiful, but needs to be more original.
I enjoyed your game a lot, because it was like Auditorium. But, well, that's a problem too, because it looks exactly as a copy of Auditorium!
That's not to say it is bad, of course. You did a good job in the creation of levels and the music selection. But you should have tried to add more of your own ideas to make something more that what could be seen as an "expansion pack" or "extra levels" for that game.
The color splitters and mergers were a good addition that kept it interesting and demanded a different thinking, but the graphical aspect was basically identical, as well as the main mechanics, thus it didn't succeed at creating a new and original atmosphere.
You should definitely make a sequel, as you showed a good creativity for the levels and music, but take advantage of such creativity to redesign other aspects of the game too.
