The first time to write such a large JS program, code volume first broken 300 of the page, but also is pure JS, no library or frame ...
On and off written four days finally finished, in addition to feel himself through this game, JS improved a lot, but also cultivate their own control of the code. Although not use to object-oriented, but I am strict with myself, more than 90% functions without annotations can not be more than 10 lines, easy to write and easy to update maintenance.
