What a great game. Such a perfect addition to newgrounds, and the medals make it so addicting. At first it was very difficult, but just a little getting used to had me be unstoppable, lol.
Here's a tip for the Walrus boss: You'll know where he's going to throw the ice cube by seeing what hand it's coming from. If it comes from his right hand, slide. If it comes from his left hand, jump.
Anyway, after getting all the medals I just had to review this game by saying it is just awesome. Keep it up, I would love to see a sequel!
