PLS HELP

I love this game... WHEN IT WORKS. Half the time i try to open it it crashes. I have an IPOD touch 4g with IOS 6.1.6 and the game keeps crashing. Crashing aside, I only have a couple problems. Like most people, i want grenades and a melee attack. But i also would like it if you tilted the screen to look around. I also would like to be able to USE the iron sight on my gun so pls add a button for that.
