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...

Thanks for the input, guys!
2 New maps up!

Thanks for the advice Edmund, I've added links to the images. 

kyle, there are camera bounds in Bandage and Cliff Division (the 4th and 5th maps I made). I left anything regarding the camera alone for my first couple of maps. Quite frankly, I was too lazy to go back and bound the other 3. 

What do you mean by "fix the camera"? Do you mean making boundaries for them in the maps that there aren't any boundaries?

And thanks for the advice on looking to the blog post for some more advanced stuff, I'm sure everything on there'll be quite helpful.

Thanks!
