I've just released my newest game 'Mixed Macho Arts'! It's a physics based one-on-one fighting game that's at it's best when played with a friend! There's also a challenging CPU-opponent available for single player combat and a lot of randomly generated content in three different game modes. It's a fast paced game that you can play if you have just a few minutes or if you get into it, it can keep you entertained for hours!
If you're into punching, kicking and wrestling, give it a try at: http://www.newgrounds.com/portal/view/676500
