For the first time with OpenGL opensource game animation framework, I have developed an app in 2 weeks with small logic and simple fun. I have tested this app with kids. kids love it. Even the grown one got frustrated after playing the game for the first time. no chance…show little frustration on your face. you can make the player change their face. 🙂 It is free to download, try : http://itunes.apple.com/in/app/ibug-lite/id456262809?mt=8. it is simple but hope kids will enjoy it.
