I really loved the idea and the mechanics, really, really cool! Also, the intro is awesome, and the "it's twelve hours to the deadline" to the last mission added a nice touch (I'll pretend it was the last mission because I couldn't manage to finish it).
I liked the music throughout the game, but maybe the scare sound effects could be a bit more exaggerated, both from the objects and the people scared.
In the mission with the burglar I felt the ghosts' energy depleted way too fast, took quite a few recharges to manage it.
I never managed to possess some objects, like the radios, despite them having a highlight.
In the last mission, to make all the people in the house pass away, I couldn't possess the door at some point, it seemed like the clicks didn't register or maybe something was blocking it.
Overall, an amazing game! Had a lot of fun!
