Game freezes iPad – Tetra Block - Puzzle Game Review

I love to playTetraBlock. Since I have installed it, after I finish a couple of games, when it normally shows some sort of ad, it freezes my iPad. I can’t change apps or turn it off. I have to wait for the iPad to time out and go to sleep before I can us it again. I hope there is a fix soon. Bummer!
