It's an interesting concept but it can be tough to figure out what you are supposed to do. I managed to copy and paste the symbol, but it was very difficult to be able to tell what I was aiming at, I basically spammed the copy key while moving my mouse around the towers general direction until it flashed blue, and the same when copying. An onscreen cursor or reticle would help a lot if you need to aim so precisely. The Tron-esque aesthetic is very cool and definitely makes you feel like you are in a computer. Good Job!
