I really liked the 2D sprites in the 3D environment, some day I'll try to attempt something similar. There were a lot of stuff to interact with, which is good. It took a ridiculously long time for me to recognize that I can pass through walls, but that's on me :)
I couldn't figure out how to win though, I guess the red bars above the people were some kind of haunt-o-meter, but it seemed to increase really slow even when it felt like I was hitting them with the best scares one after the other.
