It's just one level, but the rule change, the controls change, the goals change, everything about it changes. But really, this is the only level

A review of 2 meta games.
The review is a lot of explaining the joke, not much thinking about the joke or taking it somewhere.

"Who needs gameplay when you have ACHIEVEMENTS? Don't worry about beating levels, finding ways to kill enemies, or beating the final boss… there are none. Focus solely on your ultimate destiny… doing random tasks that have nothing to do with anything. Metagame yourself with ease! Self-satisfaction never felt so… artificial!"
A brilliant critique of achievement systems in games, delivered as a game. I remember being disturbed and incented by these in Burnout: revenge.
