In Titan Simulator, every time you punch you get 1 per punch, and you need 25K power in order to rebirth. If you rebirth, you will get 2 per punch, same to rebirthing more times. You'll find some pro players that have more rebirths, and you have to grind in this game. Keep punching, and you'll get stronger. Oh btw! You need Demon Sword, as it has the longest reach. and you can buy double power which increases your punches to 2. With double power and a few rebirths, you can get a few stronger!
