Dammit, why do I notice these things a month after they've been released?
Well, I do like this, but it bugs me just as much. Get rid of the first dead end, because it really boggled my mind to see an arrow sign leading to nothing. For the shorcut near the end, get rid of the arrow sign, because that confused me as well. Also, even though the midi added was above average, that still kinda bugs me as well. Do the above as I said, and I will personally make my own mp3 for Chemical Plant Zone that you can use.
Otherwise, I love everything else that was implemented here. The slopes, though fake, look very smooth, and the zoom tubes really give a nice, almost nostalgic feel to the level. Now, if only the tubes looked like those from the original level....
