Tower Fortress

Sara is as an alchemist and weapons forager. A tower suddenly appears in her village one day, releasing toxic fumes from an emitter that cause the inhabitants to become ill and, in some instances, die. To save the village, Sara has to ascend the tower and obliterate the source of the green gas.

A mysterious tower has risen! It emits plumes of noxious green smoke from
its summit making people sick. Strange creatures infest the tower but if
nobody tries to ascend it we will all be doomed!

Are you that hero?.....
