Doesnt work. Please fix.

I bought this game a long time ago because i used to play back on my Gen 2 iPod Touch (yeah, a long time ago) and it worked ok, but the save/load feature didnt work. I remembered the game today and downloaded it after seeing that it had been updated to include new lines and stuff. I hoped that the load/save function had been fixed but it had not. Additionally, the size of the usable screen is the size of an iPhone 4 screen. I have an iPhone 6Plus and Im sure you can imagine how absurd it looks.

Please fix this.
