This game is a hectic beast to play with friends, fighting each other that close on the keyboard is a riot. Throwing the skateboard was a nice touch, my friend kept hitting me with his, so I threw mine at him, it went through the screen and came back through the other side and knocked me out! It was like a crazy boomerang of death.
The wall jump was pretty difficult to do, but fighting with each other kept the game fun. Nice graphics as well, great entry! :)
