Too slow even with iPhone 5s – Smack That Gugl Review

Couldn't get past level 10 on my iPhone 3G, upgraded to a supposedly faster iPhone 4 and the game lagged to the point it was impossible to keep going on level 7, now I own an iPhone 5s which is the fastest iPhone ever and the game still lags so you can't keep playing, I find this extremely upsetting.
