Steampunk Tower is a defense game that puts you in charge of defending a tower. You will need to build, upgrade, and drag cannons within your tower to kill waves of enemies that approach from both sides of the screen. Build cannons in your tower's cellar, and then move them onto platforms so that they fire at the approaching enemies. In order to upgrade or sell a cannon, you will have to move it back to the cellar. Once you have built as many cannons as there are platforms, your tower will automatically grow another story. Try to earn the maximum number of stars in each level, and spend them on cannon upgrades.
