Interesting...
I enjoyed this game. For one thing, the graphics were excellent. You really felt like you were looking into a microscope at stuff. The graphics really evoked what (I think) you were trying to evoke.) The music was simple, but it fit. No sound, and there were times when some sound might have been nice, but that's a stylistic decision.
The control scheme was interesting. As far as I can tell, clicking the mouse never does anything. If so, I think you should mention that in the "instructions". (I mean, I had lots of trouble going through the screens of text! Eventually I figured out that you just spin the mouse around.) So, moving and hovering is what you need in this game...that's cool. The idea of a game "without instructions" is not truly original, of course, but this one worked pretty well. I think each "stage" was simple enough that it wasn't too hard to figure out what to do. (The most difficult was the one falling down the screen while little things tried to push you back up...I eventually decided that spinning yourself was the way to get it working most consistently. Am I right?)
The one thing that really disappointed me about the game is that it didn't have a conclusion. What is this weird little creature, who is "she", what's going on with "her" and how are they connected? There's no explanation, no closure. That's definitely disappointing.
Still, while it wasn't perfect, I'd say it was a worthy effort.
