Welcome to Game Development sub forum! Very often games present a totally different set of problems to solve and requires that things are done a little bit differently than normal GUI development. Standard desktop GUIs on powerful computers may forgive lots of unoptimized graphic routines and ineffective methods, whereas games especially on mobiles may need to tweak every cycle out of the hardware.
Here you can ask for advice and share your own experiences, tweaks and optimizations to make the games even better. Let's conquer the world with cute games!
