Pros:

-very fun with friends
-the boss level is fun
-the pipe bomb key level was fun
-the mazes were fun
-easy to get the concept of the mazes

Cons:

-first 8 levels way too easy for me
-the boss is too hard
-you can go on with a pistol
-you can beat the level with the barrels with a pistol by getting knocked down
-the fire pit at the start of one of the mazes was useless

Conclusion:

Overall i had lots of fun, nearly beat the game the first day i played so i found it much too easy. It's great to play with your friends and you can do it in singleplayer so a rough 85 is what i'm rating. I had a blast!
