Sounds good so far other than a few friends trying it I have very little feedback.
As the spider lowers it spreads its legs out making it easier to catch flies or get hit by newspapers.
As you go up the spider draws it's legs in making it harder to hit.
The game play isn't overly complex so there is not much to show. You tap to toggle direction, either going up or down.
At the moment there are two ways to lose. Get hit by a newspaper or let a fly leave the screen.
