How do i create a control system like angry birds?

Dear experts,

Hope you are having a good day! So, I’m developing a physics-based draggable object game and my peers suggested me to add a control system like angry bird. And I finally decided to do it. But I’m struggling with a few things like camera zoom out is not working when the control system is touch & aim, just like angry bird. Also, I have to touch and drag my finger in front of the character to make it go forward, which is not what I intended to do and it’s not really good for mobile gameplay. Please take a look at the following screen recording and screenshots to help me figure out how to fix these issues.

Thanks
