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 TowersA tower's placement is important, so when a position becomes suboptimal, pick it up and move it! How much you want to move them will depend on what type of towers you have. Long-ranged towers can be left alone for longer while short-ranged towers will need to be moved more frequently to stay in range of enemies.
Upgrade Your TowersWhen you've gathered enough crystals, move your tower to the upgrader and 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.Unlockable TowersAs you play, you'll unlock new towers to be used in future runs. Expand your collection of towers to destroy enemies in whatever way you want.
