I only have one word to describe this game. "AMAZING"
If you are looking for an indie casual game to play this is your election game.
Definitely, a 10/10 one of the best I've played in my life. I'm SERIOUS!!

PROS:

-Amazing funny graphics that make you just stare at the screen.
-Awesome music.
-Awesome super funny story and the way they tell it to you is just amazing. First time I've seen this type of story and man am I glad I got to know it.
-Huge variety of customizations to your character you can get by just playing or shopping on the community market. (around 3 cents for any one of the faces with some exceptions)
-Awesome in-game commentary.
-Local and online coop
-Achievements
-Level editor
-Steam Workshop integration

Cons
-The community isn't that big yet soo is harder to find someone to play with online unless you have friends. (not a direct game problem tho)
-Not that much of weapon variety. U get to a point where you cant use the yarns...
-This game is just too cheap for the experience it offers. Id recommend it even if it cost 30bucks
-It has a special menu your gonna have to adapt to and that is going to make you feel weird the first times u use it.
-The story is the same in every mode.

Verdict: BUY IT EVEN IF IT IS FULL PRICED. TOTALLY WORTH IT :)
