Here's are some suggestions to improve your game:
-Zoom the camera out so that the player can see their surroundings. I kept on running into spikes because I was not aware where I was going.
-Make the ghosts slower.
-This one's optional, but you can have a health system so that the player can take some hits before they respawn to the last checkpoint. I tried to fit through the spikes in one of the maze sections, but I kept on dying at that part. It didn't help that the ghosts were chasing me.
