Where's Stewie and the Dog?
The good
This game had multiplayer which in most newgrounds games you don't find, of course there was no single player. I could understand since the computer players would be cheap. Peter's voice was a good extra to the game. The movement was not bad and three places to choose from, all been thought out well.
The bad
Could have made a choice through more characters to choose from. One of the levels was very glitchy. The controls also seemed very glitchy, especially when attacking. The jumping was a bit weird, not fun to play alone.
Conclusion
Since it's the first fighting game of Family Guy, it was a good idea to go through with it, even thought the gameplay didn't add anything special. Good for a minute or two, especially if someone is a major family guy fan.
