Here's is some comments for your game:
- The game felt too simple at first but as you introduced more and more elements it become more interesting challenge also. The game felt very hectic, in a good way after getting to the final level. The pacing was good and the length of the game was appropriate for a jam game.
- I especially liked that the mechanic that you had to have the people to witness haunting for it to be effective and the paranormal detectives were also nice way to add tension. The confusion mechanic was a bit difficult to understand at the beginning but I got it at the end.
- One mechanic that I didn't like as much as the others were dogs. In many levels the timing to start haunting (just when the dog has passed) was very strict being even a bit too early or late would lead to the dog seeing you and multiple seconds will be wasted. Even when I succeeded timing ghosting right based on the dog it was impossible to take the human into account the same time and most often they just got confused. The problem was that the dog had any way saw the ghost at that point and when the delay from the barking always lasted so long that the confusion timer of the person had already ended. In short, dealing with dogs felt just random, not skill. I would suggest either changing the dogs with some other mechanic or making the rooms larger so that dealing with the dogs does not nee so accurate timing.
- I for some reason really liked the door effects (animation + sound effect). It really made the scene look more alive that the doors were responsive when characters left house and when investigator went around investigating.
- I noticed a bug that the investigator sometimes might catch the ghost from another room if the ghost is close to the edge of the room. There might be some problem with colliders there (or how you handle detecting if the ghost is in the same room)?
- Ghost felt sometimes a bit too slow. I would have liked to be able to move faster. Haunting is the fun stuff in this game so I do not want to use extra time for moving from place to place. Note however that if you end up changing the speed later, you would also need to recalibrate the level timers.
- The game viewport in the itch.io page is weirdly large. You could probably make the game page to look better by decreasing the Height and Width settings in Edit Game -> Embed options.
