Just a few days after beta 3 was released, things are going very well with beta 4 already. I have added full iOS 4 support, with fast-app switching. I have also upgraded Cocos2d to the latest version. Documentation and tutorials are really taking shape now. So after beta 4, there won't be much left until an official release. So next week might be a good estimate time frame for a submission to Apple.
Work has already started on a new game for the iPad, it's only on paper right now but the game mechanic is going to be very cool. More on this later and in another blog! :)
