Not bad, until.....

You try to do a walk through. I completed several levels before needing help, but this app locks into a dead loop of ad screens-- you cant proceed. It asks if you want to see the walk through, plays a commercial as to be expected, then goes back to the help screen, select Yes, and its more ads, ad infinitude et ad pukium.
The challenges are pretty good-- not the best Ive played, but well worthy of 3, if not perhaps even 4 stars, if not for this glitch....
