This code, with a line, with a semicolon, the statement of a line, I do not have a line to write n sentence of the smart.
This code, some places are not standardized, such as the use of anonymous functions, but not to optimize efficiency (object pool), but as a complete game, it can run up, remove import those, the core code is 20 lines.
Although only a short line of 30 lines of code, but we use the class of knowledge, objects, gradients, matrices, event processing, anonymous functions, random operations, as well as graphic graphics, such as though small spite wow
