Cool. I also love the bubbles style; it has an excellent variety, though really the contrast between bumpy and flat is there in all the styles to some extent, except Dirt where the only flat pieces are metal, which you might not want.
Even though I can't play people's LemEdit levels, I like reading level titles, partly because many of them are clever or witty in some way, but mostly because I want to make sure I'm not duplicating them with any of my titles. I know it's not a crime to duplicate someone's title accidentally, but for some reason I have a real problem with using a title someone else has used.
