Etherium

Professor Bambo, the great scientist, was able to find the 5th dimension, and to pick out a new type of energy from there - he called it etherium. Of course, our hero could not stop himself from studying the unknown. And so, he discovered that etherium could behave like a normal physical object, or like an electricity, in some sort of way, and every device powered with this mysterious energy was working far better than before! But nothing went unseen for the dimension itself, and it decided to destroy our professor. In order to banish the intruders, our pacifistic (and weaponless) professor will have to sacrifice every single ability he manages to duplicate from them. You are the one, who’s gonna help Bambo destroy waves of etherium-possessed enemies using his new etherium shield technology, and you are the one, who will lead the world to technological progress!
