Nice idea, the kind of game i expected to see whith your ghost previous selfes. However its a pet peeve of mine but when joining a jam try to offer a web build. I see you used godot, if you also used gscript then exporting is very easy and makes playing so much easier.
That being said i liked your art/creepiness of the game. I did notice the ghosts where a bit bugged though but the actions were still done correctly is was more a visual glitch
