Really cool game, love the concept, addictive, not enough levels. What would be cool is a "free mode" where you can experiment and create whatever you want, and user-created content, where others can try to recreate what others have made.
The gameplay was really fun and original, although a bit short and easy, (although I admit I did have a bit of trouble working out that last one) and I also thought the narrative was quite clever and original, too, for the gameplay. Until the end. It was kind of a cliche ending, a bit too spelled out, and I think I might've preferred it if you didn't make it relate to reality, and maybe let others interpret it as they will. Music was well-suited and really set the mood well.
