The concept is one of the best I've seen so far, but it's tough to dodge any of the bullets since they're a little too fast. It would have been great if there was like a jump so that you have a bit more room to dodge the bullets and push the risk with how many you fire. I thought about what if you could shoot a bullet at one of the ones a ghost fires and they collide and save you from certain death too. Lots of room to make the game fun.
Very creative and has the potential to be very, very good. Great work.
