well here is simple rain consisting of 5 png sprites creating every at random (to200/second) on a random edge of the top screen, just like the snow flakes were.
the rain sprites are having effects like lens, or distort, and that makes it more beautifull, but more like usefull for making waterfalls or rivers...water on surface effect.
the rain will probably look better if effects disabled.
ah yea some forest image used as background and the char from platform school.
