Ok, here's my review:
The beginning was OK, it seemed to me the decos were really fitting, but the 3D floor looked a bit too simple and awkward. Then you have a cutscene, go through some stairs and oh my! No!!! There's an easily solved mistake that you should fix as soon as possible. When in the switch room, you can look at your left and you can see the level background! Here, a pic:

Adding a mini cutscene or sound effect for the switch would be excellent. Then there was this weird looking stairy thing floating there after the cutscene. At first I really didn't know what to do, but I managed to get to the next floor after a while. Then there was this spiky challenge in the stairway. Man, you need some patience if you want to go through this! Well, not really once you understand the pattern. The score bubbles were a nice touch as a hint.
More stuff, and then there is this electricty part in the stairs. Though a bit tricky, it was one of the most professional challenges in the level so far.
I was loving the lightning effects, well done with that :D
Ok, one of my main problems here were the curscene triggers. In the cutscene before the bridge thing, I had already fallen of the bridge when it started. And when I was in the lab (awesome monster costume :D) it started after I had gotten past the Doctor. Oh, and there was a random gadget visible here:

I would suggest making clearer what the boss battle is about, where you have to shoot the machines to turn them off.
Time for... THE GRADES!!!:
Gameplay: 3/5 Nice ideas, but some were confusing or bad executed.
Graphics: 4/5 Even though some parts were quite too simple, it was the overall best aspect of the level.
Sound: 3/5 Some switches didn't have sound effects, so I couldn't really know if they worked. Nice music choice.
Overall: 3/5: Don't misunderstand me, I thought it was a pretty neat level with nice ideas and a good story, yet there are lots of thing that could be improved. I know we all begin with simple levels, and this surely deserves much more plays than the 12 plays it had when I played it. Hopefully you'll get better noticed in the future :D
