Buttons to small

I am a fan of this series however after downloading cubemen 2 on the iPhone 6+ I am a little upset I cant play. The buttons in the game are so small even on this 6.4 in screen. They are positioned along the edges and grouped tight together. I have small hands and my pointer finger covers all 4 buttons on the bottom right during game play. Since the game has zoom ability they really should have made them larger as there is still a lot of open space on the screen to where they will not effect game play.

Please release an update with an option to enlarge the buttons during game play. Once this is done I will be able to play and will gladly give 5 stars
