Description: Regular script, not bearing semantic loading, but fans of reality (and not only) should be. Now there are in the game such natural phenomena as the ebb and flow. Unlike programs for editing the level of water, the water comes and goes smoothly without the games, and (most importantly) changing the water level only in sea, Lake at dam, swimming pools and zadniâh sites are unaffected, also does not affect the existence of waves (as opposed to a program that was one level everywhere).
