Also is the front end, unfortunately I do not the game front end, some small regrets.
However, relying on their own a little more than the average learning ability, or squeeze out a lot of time to self-study some gadgets (let's call him a gadget).
They are groping to do, the code is very simple, just work half a month, very helpless. Give yourself some clues about how to keep some memories.
(Because the company is the Hong Kong side, so are the traditional system, but only use my crappy English comments ....) More helpless is to take a very name for yourself--snow)
