A cool concept and clever interpretation of the theme!
My first impression was that I was going to be an entirely non-physical ghost, interacting indirectly through hauntings...
But then the guard started chasing me! There was no chance for me to hover my mouse over anything at this point or appreciate any of the detailed descriptions/writing for the arcade machines. It was cool when I was able to phase through the desk to avoid the guard temporarily... but i don't know if that was intentional. I think it'd be cool to lean more into being a non-physical ghost and phase through walls and stuff! Or what if instead of guards chasing YOU, it was a patrolling repairman who fixes haunted machines?
EDIT: I just realized you can hide in plants.... This does change a lot!! Unfortunately I did not discover that on my own at first because I was too busy running
The art was excellent and i love the ghost character, music was a great fit, and i appreciate all the attention to detail in the UI! Great work!
