For those wondering
I'm pretty sure this game isn't exactly a 'joke' but more of a cynical look at independant games that experiment with things not usually included in games. See the Pc/mac game 'passage' for example.
It's similar to games like 'achievement unlocked' and 'you have to burn the rope' in that they are also made to prove a point about different types of games.
So yeah, it's not a bad joke it's just proving a point - or at least that's what I thought.
