Porta-Tower

Porta-Tower is a roguelike tower defense game where you can pick up and move your towers to better cover the enemies' path. Move Your Towers A tower's placement is important, so when enemies move out of range of a tower, move it to a new position! Upgrade Your Towers When you've gathered enough crystals, move your tower to the upgrader to upgrade it.

Be careful, though, as moving a tower to the upgrader will take it out of the defense until you put it back in position. Choose Your Towers And Your Enemies Pick not only which towers you'll use for your defense, but also the enemies that you'll have to face. Build a set of synergistic towers and a roster of enemies that are weak to them!
