While the game idea is interesting and the story of Bloody Mary is a good one to work with, I feel like a bit more polish is needed.
One of the things I noticed is that when you press q to run, it would use up the bar even if you are out of danger. It would suit the game a bit more if it was more of a toggle ability that refills when not in use instead of a one time press to use.
Another thing I noticed is the fact that Bloody Mary herself keeps respawning at the edge of the screen. It'll help her creep factor more if she despawns when the player outruns her off the screen and respawns in another area.
Last thing I noticed is you used shapes and loud noises for your death/jumpscare. I recommend tailoring the death/jumpscare to each entity type. (I.e Ghosts gets a possession death while Bloody Mary gets the screen slash and shake death with accompanying sounds.)
Overall a decent foundation for the game to improve on.
