About Porta-Tower

Porta-Tower is a roguelike tower defense game where you move towers to cover the enemies’ path. You choose the towers in your defense and the enemies you will face.

Position and upgrade towers

When enemies move out of a tower’s range, you can pick it up and move it to a new position. After gathering enough crystals, take a tower to the upgrader to improve it. The tower is temporarily out of the defense while it is being upgraded, and must be returned to its position afterward.

Choose your lineup

Select towers that work well together, then choose a roster of enemies that are weak to them.
