Thanks for the input you two!
I use sloped surfaces out of habit (from N+ levelmaking) and in attempts to spruce up the place. I've tried to cut back on them in the newer levels (see first post).
And sorry about the bandage girl thing, the whole time I thought that she actually WAS touching the floor... thanks for pointing that out.
The first post contains a download for 7 levels (two of them are already separately in the first post). Let me know what you guys think of 'em, you're really helping me out! Apologies if you didn't like the Black/White/Grey scheme...
