First of all it looks like a fun game, but either i don't understand it or it does not fully work.
Some small issues i found is that the character can run off screen to be never found again. So can the ghost but since it flies that works out okay and might even be intended.
One of my pet peeves is to always include a web build for people for better playing, in this case doubly so because my virus scanner initially quarantined your game. I did an another scan to make sure it was a false positive and i guess it is. But a web build would prevent that.
One other thing is if you make your game full screen please include an exit button, its so messy to have to crtr alt f4 a game to exit
