I am just about over this. The developers HAVE to scale the program down. It is very heavy on resources. On reading other reviews there are many users having the same prpblem. I am so over playing a 'very hard level' and investing 'power ups' to that level and with two moves left, and it looks liks I will win the level and the level CRASHES back to my devices home screen. It is just not good enough. Thank God I have NOT paid for these 'power ups'. Fix it.
