I really like this game as it's one of the rarest ones where the developer responds to public comments, also awesome game though I liked the previous part more c:
If you want quick level up at starting of game first use the broken tauron on the enemy and then finish him with a shot of the tire iron on his head while airborne, you'll get achievement "DEATH FROM ABOVE" and you'll be promoted to level 2
What do you prefer about the previous one?
