Should I buy the game?

Can someone who knows the game well summarise what the games like to play, and their enjoyment. Maybe how many hours of gameplay, challenge to 100% and other stuff?

I just like how funny it looks and that it doesn't take itself seriously at all. Seeks like a nice break from other games I play, but I still want a game I can sink my teeth into and learn, yknow? Have a unique experience instead of doing the same copy paste as everyone else
