Finally, a Flash adventure game that I can play without wanting to kill myself five minutes in. (I mean myself, not in Johnny's case...)
It's... frighteningly accurate how much of the movie you've got down here. The locations look spot on from the movie, the football tosses were done in the same way (at least from what I remember), so on. It's great to see a lot of the subtle references too. Aside from all the usual catchphrases, which thankfully you don't dwell on too much, you've also got some of the more subtle jokes, like the psychiatrist guy getting killed (for anyone wondering, he disappears halfway through the movie and is replaced by that guy with the huge hair) and the police station trip.
It's slow, but that's kinda the point. It's a realtime reenactment of the movie and you get to suffer alongside Johnny. If anyone playing this finds it boring, this isn't the game at all for you. Looking at the reviews, it seems some people never heard of the movie, and unless you don't want anything spoiled (it's not much, trust me) I'd suggest looking up a summary of the movie and some of the stories behind it's infamy, it really helps a lot.
Excellent game. Anyone who decides to make an adventure flash in the future should play this first as an example of what to do right.
