Loved this game but now cant play

I recently reset my iPad to start over with storage and now cant log back into by old account, no biggie I figured Ill start from scratch. But 2 minutes into the first episode I cant even continue - the lag is so bad I cant do any of the controls, the music and sound doesnt play on speaker, only headphones ( iPad plays music/videos aloud perfectly well) and Im stuck having to watch the same cutscenes over and over because I die before I can even reach a save point, and theres no way/option to skip through the dialog. I was excited to play the final episode and now I cant even play any, will gladly try again if problems are addressed.
