Time the flow in Dambuilder

Let's go back to the original inspiration for Dambuilder. It has this name in memory of the childhood activity of making dams in little streams. The goal in building dams like this is to make the water move through the system as slowly as possible, but without the water getting stuck in any one place (and overflowing one of the dams)

. You can use the cursor tools to make new walls and move them. Click with the Equals cursor to copy, prick with the Pin cursor to delete, drag with the Hand cursor to move. This is how you 'play the game'.

 How do you tell how well you're doing in Dambuilder? We need to have a score that calculates the average time that it takes a critter to fall from the top to the bottom of the screen. We reset the critters' ages when they wrap bottom to top

. And we need some kind of penalty if a critter gets stuck for too long. Perhaps if a critter's age gets larger than some MUSTBESTUCK time value, then the critter explodes and destroys everything near it, including the dam that it's stuck behind. So your goal is to get the critters moving along as slowly as possible just short of being stuck and destroying the dams.
