I really enjoy this game. I have played through all 3 difficulties and each one does require more effort yet not impossible to master. I love the different modes and visual styles. I can honestly say you hit home with quite a few of my favorite classic gaming memories while making them fresh at the same time.
My only trouble is trying to earn all of the speed achievements... especially on the pong levels!
I have no problem with using the 3800 battery but I did feel that this case made the phone very bulky so I returned it. That is the only reason I took away 1 star. The quality is impressive and is worth the price but it just wasn't for me.
