Shooting feels great! Learning how to switch between the two worlds felt nice in the beginning too. I wanted to be able to keep the spirit world clean by fighting enemies one at a time, but they came too quickly for me to get rid of given the long process. One cool move I was able to do was to fire a blue and then a purple bullet at a far away enemy, then switch into the spirit world when the blue hit them, purple shoot them in the spirit world, then switch back to let the first purple bullet finish them off. With a bit of balance this could be awesome!
