Hey I also made a simple game where you kill ghosts but I took a lot longer to make it XD.
This is fun! I liked how the ghosts telegraph moves with their faces. I assume I have to git gud to shoot-jump over the big slidey ghost. I like the pause effect when you die and then you can jump right back into another round.
I think a few more tweaks would make it feel more fair. It was hard to time my dodges and I wanted an ability to stand still while pointing my gun.
Well done!
