This is a really neat concept, the backstory got a chuckle out of me. I found the game difficult having to manage all 4 ghosts and often times the game would end before I got the rest of the ghosts out in the maze cause I wasn't paying attention. Possibly having some leadway to allow the player to route the ghosts before pac-man starts might help negate this issue? (I only really dabble in game art not the mechanics behind it <:D) Overall, I think you should keep building upon this!
