Thank you so much for such a nice comment! I can't tell you how much that means!
And yeah, getting killed by your ghosts when you're on top of them was a tough choice to make. It used to not be the case, but then I let a friend test my game and he found a way to stay alive forever by just standing still for the entire game or camping in a corner, since your ghost couldn't kill you this way it made the game insanely easy.
I did add the 3rd enemy after that, which shoots bullets directly at the player when killed, to furthermore prevent this cheesy technique, so maybe now I can go back to the ghosts not being able to kill you if you're standing right on them, it's something I'll definitely need to experiment with!
Sorry for the little annoyance, I really hope this didn't make your experience with the game bad, and thank you for the feedback!
