Wow everyone that uses guides are total losers, i made it to level 30 without cheating and since I'm stuck I'm not going to be cheap and look at the walkthroughs to get a badge I don't deserve.
all the modes r easy. for classic i just load up the game and open up another window and do other stuff. avoider is way too easy i just stopped after a while. chase has the same problem, way too easy because it stops gaining speed after a certain point. With that said, this game is pretty easy for a master of Dont Shoot The Puppy.
I like this game, very well done. The only thing I would suggest is that when you have a bow or some long range weapon it's too easy to get trapped in a corner by someone who has a close range weapon.
