Scirra adds an arcade and all I can say is wow! Scirra's arcade is absolutely amazing. It has a lot of social networking linkes which is really important. And now it has an embed feature so you can add the games to your blog or website. This is so awesome. On top of all of this they have little game cards that you can use to promote your game. I can't wait to see what comes up next!
Again, every update Scirra gives feels like Christmas.
