Ooh, this is beautiful! The tilesets are lovely, though I dock you points for not making them yourself. The sound is fitting, but it's noticeable when it loops. The custom objects are amazing! I wish I was that good at animating.
The whole thing is very un-knyttish, but that isn't a bad thing at all. If I were to give it a score from 1 to 10, I would say... 7.7/10. It was just a bit short, and would benefit from some challenges. It kind of lacks gameplay.
I really liked this. Very good custom objects, and very good custom object use. This level is awesmoe.
However: did you ask Nitrome for permission to use their graphics? If you didn't/don't, then this level will be deleted. (Unless they have some sort of standing "you can use our stuff" policy.)
A few bugs/inconsistencies:
On the screen where you get the virus, if you go to the left side of the screen, there's a stray sign object so you can see what the guy on the right is saying again.
After putting the disc in, on the way out, the guy says "destruciton" instead of "destruction", and the word "to" is missing between "ought" and "leave".
After exiting the pipe after this, as the trap closed, it closed on Juni's head, leading to a brief wallswim.
That guy promised to follow and explain, but I never saw him again.
On the way between where you get the umbrella and the bit where there are a bunch of fans, one corner tile of rust and garbage and stuff, and the little bit coming off its left side, is solid, whereas like all other such tiles are not.
The dealy with the hanging cage things that you jump across- the shift there makes the default noise, which is really weird in context, where the mechanical shift noise would be much better. (Also the cage dealies don't make a sound when in action, unlike most all other machinery.)
wow. terrific level. although it was hard to see what was going on sometimes, this was one of the most detailed and creative levels i've played. great use of COs.
some glitches, not sure if they've been reported yet:

also, on (1003, 1006) [i believe], if you speed upwards through it with your umbrella, you somehow miss the shifts, the big closing CO forgets to spawn, and you hit a void up top. not sure how that works, but it happened with me.
great work.
