Under the watchful eye of Mr. Towers, assemble buildings from color-coded construction blocks before the conveyor belt backs up in this unique combination of block dropping puzzle inlay action and city-building simulations. Revitalize 48 different cityscapes as you build homes, factories, shopping malls, schools, fire stations, and more! Use power ups to bulldoze unneeded buildings, freeze, reverse, break up or detonate construction pieces, and spray paint new colors!
