By request, this version has single-axis pseudo-random movement, instead of movement all over the screen.
A fish starts out in the middle of the screen. In the X-axis level, you attempt to move him either to the left or right. In the Y-axis level, you attempt to move him up or down.
The score changes each time the fish hits the edge of the screen (down by one point in one direction, and up in the other). Get as far from 0 as possible, in either direction.
The lily-pads are strictly decorative in this game.
