Multiple, by 
Wow. You know, when I first saw this level, I thought “wow, this looks bad.” But you know what? I was right.
The level consists of a large empty place with a turtle shell in it, and two dead end rooms on either side. The dead end rooms have layer 3 pillars in them, which not only do not have a transparent background, don’t have layer 3 above and below.
All the walls are the same tile – an animated block which changes colors repeatedly. There’s a turtle shell in the middle of the level, the “football”, which you are to shoot back and forth into the dead end rooms. Judging by the rest of the level, I was pleasenty surprised to see that the turtle shell generates, if stomped upon unkindly.
Edit:
No, it’s not an original idea. It’s been used many, many times before.[This review has been edited by Violet CLM]
