Seriously, who did it? Because it's pretty brilliant. Most every Portal 2 review I've read reaches for the SMB yardstick to describe the innovation and simplicity and geometric progression of ideaspace that the portal gun creates. So giving one to Mr. 8-Bit Superstar's a perfect idea, and in under two minutes he come sup with some winning ways of using it. In Mario's adept hands, not even the cake may be a lie any more.
