It's good, pretty hectic dragging stuff around to make the clock tick faster. 1 big downsides and 2 minor gripes with it tho. Big downside is it is way too heavy for playing in the browser. And my gripes are the slowed end of scroll to reach a selected floor making me wait a few extra seconds to make squares at the very bottom visible and the elevators more got in the way than helped really since I could be a lot more effecting by holding a square and then moving floors with the arrow keys.
