Rovio is clearly hurting for sales...

...if they force an ad on you after every level.

I purchased this app (and several other versions of angry birds as well) years ago and it was not like this. I have recently reinstalled for my 4yo to play, and its simply not possible for him to use - he manages to click the ridiculous ad after every level and open the App Store, resulting in him becoming lost. I will never purchase another rovio app.
