Very good idea. Work on the physics a little bit, I noticed some of the little green balls bouncing in seemingly random directions and speeding up and slowing down.
Sorry for commenting three times, but I wanted to say that I take it back. If you just ignore the fact that you can see the words through walls and actually get past the first two rooms, it's a pretty good story.
Sorry, but I had too. :P If, like others have been saying, you couldn't see the text from behind and through walls, I might be able to play it through. And maybe some dark lines on the edges of walls to say where one ends and another begins, again, like others have been saying.
thank you.. that makes me feel better :) and I fixed the beginning :)
