"Just wondering that Mans games are Not playablenon the Ipad??"
What do you mean by "Mans" <-- Does this have anything to do with game creation?, I know what this means and hows its used in a sentence. But your asking for professional help from people who are educated. This is not the mannor you speak with on the forums. I myself am only 17 but I speak to users with respect.
As to your question.
If you made a game with Construct2 there could be many reasons why your game is not working on the IPad,
You might now be using the touch plugin, if your game is using the mouse plugin you need to change it to the touch plugin, there both very similar.
Your IPad might not be able to handle the game, HTML5 is a relatively new technology so it's not going to perform as well as using other programming languages.
If your game is using allot of physics then IOS devices are known to have crappy performance when using the physics object.
Construct2 is a great tool, But for now intense mobile games are a little way away.
