There are some cool ideas here. It might have been nice to be able to see the victim's pathing and time, as well as get an idea of how long each scare will take to execute.

I liked how you play as a the ghost instead of the victim

Loved the music, Overall pretty good.

I had a hard time understanding the game mechanics eventhough I played the tutorial. Couldn't finish it but I loved the sounds and visuals.

Tutorial is always a good feature in a game, thank you for the effort, it helps a lot. But it could be a bit more explicit, even after the tutorial I was not sure about the gameplay mechanics. But nice UI and sound desing, really liked that. Nice submit after all, GGs!

I did not expect a giant black monster to come out of that painting, I thought it was just going to float around or something. 

That NPC really tripped as that ungodly creature emerged from the picture right before his eyes :)
You got an interesting idea and gave me a good impession of it. As others said, it would be nice to have more than one shot with some objects. Right now, the energy system and the inteactable object seem correlate exactly. For ideas: You could implement something to distract the NPC or lure him in on room (which takes energy) e.g. a radio, televion, etc.
Nice work!

There are some really unique ideas here! The core mechanic of acting as a ghost possessing objects is a great inversion of the horror game theme. And I really loved all the animations, especially the person's eyes bugging out when they get scared. I would recommend iterating on the energy bar idea some more, as it is, it doesn't have much of a use when you can 'lose' a level before it is depleted. I would also recommend adding some way to reset the interactable objects, maybe you can pay extra energy to reset them? But I am sure that with some more polish, this will turn into something truly special!
