Ah, I see what you mean now. I've tried to make the game playable at different aspect ratios, and so making that level just have a plain screen wrap wouldn't really work.
I'll see if I can think of some solution (changing the height isn't a bad idea but would mess with the level design a bit), but as it is I don't feel it's too much of a problem.
I definitely appreciate the feedback, though, and thanks for elaborating!
