Consider

Hey, I am a huge fan of both simple planes and simple rockets, but my favorite game of yours is kernel space program!! You should seriously consider releasing KSP for iPhone 6/6s (because they as of right now have better processing power). I dont know the possibilities of this, but if you price it at around $7 I bet you would make tones off it!
