Is Madworld worth it's current price of $19.99?

Bought it for 11 euros.Spent 4 hours on it and that's all.I usually buy last year's games and I want to get 1 hour out of each euro I have spent.I feel ripped off but that's probably just me.
I think 20$ must be ok for most people.

PS:It's not that i didn't like the game,it's just that it has way too many problems and no replayability at all.

I agree with the comment about the lack of replayability. 

I don't know if I want to ever play Madworld again.
